BREAST CANCER

EpidemiologyBreast cancer is the most prevalent cancer among

women and affects approximately one million women worldwide.

Prevalence ( epidemiology) is the total number of cases of a disease in a given population at a specific time

Prevalence is the number of all new and old cases of a disease during a particular period.

Incidence is the number of new cases of a disease diagnosed in one year.

EpidemiologyBreast cancer accounts for 30% of all female

cancers (UK). Men can also develop breast cancer,

accounting for 1% of cases diagnosed annually (UK).

Breast cancer is the most common cause of cancer in women (U.S.)

The most common cause of death in women between the ages of 45 and 55 (U.S.)

RISK FACTORS

SexBC in men is rare (> 1% from all malignant

tumors)Sex ratio, women / men = 100 : 1

Age

Ageing is the most important RF

RISK FACTORS

Geographical variation

There is quite a difference in incidence rate of breast cancer between different countries.

The biggest difference is between Eastern and Western countries - low to high

RISK FACTORSReproductive factors- Women who start menstruating early in life

orwho have a late menopause have an

increased risk of breast cancer. - Women who have natural menopause after

the age of 55 are twice as likely to develop breast cancer then women who experience the menopause before the age of 45.

RISK FACTORS

Age at first pregnancy Having no children and being older at the

time of the first birth both increase the incidence of breast cancer.

The risk of breast cancer in women who have their first child after the age of 30 is about twice that of women having their first child before the age of 20.

The highest risk group are those who have their first child after the age of 35

RISK FACTORS

Inherited risk Up to 10 % of breast cancer in Western

countries is due to an inherited factor.It is not yet known how many breast cancer

genes there are, but to date, two specific breast cancer genes have been identified (BRCA1 and BRCA2).

RISK FACTORSPrevious breast disease Women with certain benign changes in their

breasts - severe atypical epithelial hyperplasia. Radiation Women who received radiation to the chest as a

result of repeated X-rays for tuberculosis, age 10 and 14 years.

Women with Hodgkin's disease who received radiation therapy to the chest have an excess risk of breast cancer.

RISK FACTORSHormone replacement therapyAmong current users of

hormone replacement therapy (HRT) and those who have stopped using it one to four years previously, there is an increased risk of breast cancer.

This increased risk is very similar to the effect of a delay in the menopause by one year.

RISK FACTORSWeightBeing overweight is associated with a doubling of

the risk of breast cancer in postmenopausal women whereas amongst premenopausal women obesity is associated with reduced breast cancer incidence.

Alcohol intakeSome studies have shown a link between the amount

of alcohol people drink and the incidence of breast cancer, but this relationship is not consistent and may be influenced by dietary factors other than alcohol.

RISK FACTORSHormonesWomen who take the contraceptive pill are

at a slight increased risk while they take the Pill and they remain at risk for 10 years after stopping the drugs.

MAMMOGRAPHY

Mammograms are a good way of identifying abnormalities in the breast.

Used for women over the age of 35.

In younger women the breast tissue is more dense, which makes it difficult to detect any changes on the mammogram.

MAMMOGRAPHYHowever, mammograms are not perfect:

A mammogram may miss some cancers. (The result is called a "false negative.")

A mammogram may show things that turn out not to be cancer. (The result is called a "false positive.")

Breast cancer-mammogram

BREAST ULTRASOUND SCANAn ultrasound uses sound waves to build up a

picture of the breast tissue.

Ultrasound can often tell whether a lump is solid (made of cells) or a fluid-filled cyst.

It can also often gives the information whether a solid lump is likely to be benign or malignant

FNACWill show whether the lump is full of fluid or solid.

Can allow a sample of cells to be removed for examination under the microscope –cytology.

This is a very accurate method of finding out whether the lump is benign or malignant.

A fine needle aspiration (FNA) is a quick, simple procedure done in the outpatient clinic

NEEDLE CORE BIOPSYCan allow a breast tissue specimen for

histological and immunohistochemistry exam.

Can obtain a preoperative diagnosis resulting in more appropriate decision of therapy.

Core biopsies are often done using ultrasound as guide to the lump.

Local anaesthetic is injected into the area first to numb it

OPEN BIOPSYA biopsy is the only way to tell for sure if cancer is

present.

An incisional biopsy takes a sample of a lump or abnormal area.

An excisional biopsy takes the entire lump or area.

This procedure is done either under local anaesthesia or general anaesthesia.

Types of breast cancer

Early pathologists classified breast cancers into 'invasive ductal' cancers and 'invasive lobular' cancers, believing that invasive ductal cancers arose in ducts and invasive lobular cancers in the lobules.

A more logical classification divides tumours into those of 'special' and 'no special' type.

Types of breast cancersInvasive carcinoma of no special type is also

commonly referred to as invasive ductal carcinoma. It is the most common type and accounts for up to 85

% of all breast cancers.

Special types of tumour have particular microscopic features and these include invasive lobular carcinoma, invasive tubular, cribriform, medullary and mucinous cancers.

Many of the special-type cancers have a better prognosis - in other words the patient has a higher chance of survival.

Stage Information

The American Joint Committee on Cancer (AJCC) staging system provides a strategy for grouping patients with respect to prognosis.

Therapeutic decisions are formulated in part according to:- staging categories - lymph node status,

- estrogen- and progesterone-receptor levels in the tumor tissue,

- menopausal status, - the general health of the patient.

Staging of the breast malignant tumour Stage 0 Ductal carcinoma in situ (DCIS) almost always completely

curable.

The following stages of breast cancer are known as invasive breast cancer: Stage 1 The tumour measures less than 2cm. The lymph nodes in the

axilla are not affected and there are no signs that the cancer has spread elsewhere in the body.

Stage 2 The tumour measures between 2 and 5cm. or the lymph nodes in the axilla are affected, or both. However, there are no signs that the cancer has spread further.

Stage 3 The tumour is larger than 5cm. and may be attached to surrounding structures such as the muscle or skin. The lymph nodes are usually affected.

Stage 4 The tumour is of any size, but the lymph nodes are usually affected and the cancer has spread to other parts of the body. This is metastatic breast cancer.

Hormone receptors

Many breast cancers have receptors for the hormone oestrogen.

When oestrogen attaches to these receptors, it causes the cancer cells to grow.

If a breast cancer has a significant number of oestrogen receptors it is known as being oestrogen-receptor positive ER+

If it doesn’t it is known as oestrogen-receptor negative ER-

Knowing whether the tumour has oestrogen receptors or not helps the doctors to decide on the best treatment.

Hormone receptors

A tumour that is ER+ is likely to respond to hormonal treatments|, whereas a tumour that is ER- will not respond.

Some breast cancers have progesterone receptors and are known as progesterone-receptor positive (PR-positive).

Usually, cancers that are ER+ will also be PR+.

Progesterone receptors are less important than oestrogen receptors in predicting the likely response to hormone treatment.

HER2 receptors

Some cancers have receptors for a protein known as HER2|.

Tumours that have high levels of these receptors are known as HER2-positive and may respond to treatment with drugs such as trastuzumab (Herceptin®)|.

HER2 is a protein found on the surface of certain cancer cells.

Some breast cancers have a lot more HER2 receptors than others.

In this case, the tumour is described as being HER2-positive.

HER2 receptors

Tumours that are HER2-positive tend to grow more quickly than other types of breast cancer.

Knowing if a cancer is HER2-positive can sometimes affect the choice of treatment.

Women with HER2-positive breast cancer can benefit from a drug called trastuzumab (Herceptin®).

Herceptin only works in people who have high levels of the HER2 protein.

Treatment overview

The treatment of breast cancer is individual for each woman.

The treatment depends on many factors, including: the stage and grade of the cancer age whether the cancer cells have receptors for certain

hormones (such as oestrogen) or particular proteins (such as HER2).

Treatment overviewMost primary breast cancers will be treated

with surgery.

All or part of the breast tissue may be removed.

If the whole breast is removed (mastectomy),

Breast reconstruction may be carried out, either at the same time as the initial surgery or later.

Treatment overview

Sometimes chemotherapy| or hormonal therapy| may be given to shrink a cancer before surgery -this is known as neo-adjuvant therapy.

After surgery, radiotherapy| will be given to any remaining breast tissue, and may be given to the chest wall if the breast has been removed. This is to make sure that any cancer cells that may be left in the area are destroyed.

Further treatment includes hormonal therapies, chemotherapy and/or a drug called Herceptin|®.

Factors which affect the chance of the cancer coming backthe size of the tumour

lymph nodes status

the grade of the tumour

Receptor status for oestrogen or particular proteins (such as HER2) Cancers with oestrogen receptors are less likely to recur in the short term, whereas those with HER2 receptors are more likely to come back unless Herceptin is given.

SurgerySegmental excision (breast-conserving

surgery or breast-sparing surgery) Followed by radiotherapy aimed to destroy cancer

cells that may remain in the breast.

Mastectomy – excision of the whole mammary glandStudies have found equal survival rates for breast-

sparing surgery (with radiation therapy) and mastectomy for Stage I and Stage II breast cancer.

Breast-conserving surgery

Segmental excision – excision of a quadrant till MP muscle

This is usually followed by radiotherapy, treatment to the remaining breast tissue.

The pathologist looks to see whether there is an area of healthy cells all around the cancer – this is known as a clear margin.

If there are cancerous or precancerous (DCIS) cells at the edge of the area of breast tissue that has been removed, there is a higher chance that the cancer will come back in the breast. 

In this case, more breast tissue will need to be removed or even a mastectomy.

STAINING WITH CHINA INK TO ASSESS THE MARGINS OF RESECTION

FREE OF TUMOUR CELLS / PRESENT TUMOUR CELLS

Radical surgery

Removal of the whole breast (mastectomy) may be necessary if: The breast lump is large in proportion

to the rest of the breast tissue. There are several areas of cancer cells

in different parts of the breast- multicentricity of the tumour.

The lump is just behind the nipple

Mastectomy

Simple mastectomy and sentinel node biopsy or node sampling removes the breast tissue and the lower lymph nodes, within the axilla.

Sentinel lymph node biopsy is a new method of checking for cancer cells in the lymph nodes. A surgeon removes fewer lymph nodes, which causes fewer side effects. (If there are cancer cells in the sentinel lymph node, an axillary lymph node dissection usually is done.)

Modified radical mastectomy removes all the breast tissue and all of

the lymph nodes in the axilla. It may also be referred to as a total mastectomy and axillary clearance.

Radical mastectomy removes all the breast tissue and the lymph nodes in the axilla, together with the muscles behind the breast tissue. This is only done if the cancer invaded the pectoralis muscles.

Surgical complicationsLocal pain and tenderness- pain relief with

painkillersWound infectionBleeding wound

Numbness and tingling of the shoulder and upper arm due to nerve damage during axillary dissection

Lymphedema of the arm due to impaired lymph drainage following axillary dissection.

Radiotherapy for breast cancer

Radiotherapy treats cancer by using high-energy rays to destroy the cancer cells.

The treatment is often used after surgery for breast cancer, most commonly after segmental excision.

It may occasionally be used before, or instead of, surgery.  

Radiotherapy can cause side effects such as: skin soreness and tiredness, but most will improve once the treatment has

finished. 

Radiotherapy for breast cancer

After a mastectomy, radiotherapy to the chest wall may be given if there is a risk that any cancer cells have been left behind.

If a few lymph nodes have been removed and these contained cancer cells, or if no lymph nodes have been removed, radiotherapy may be given to the axilla to treat the remaining lymph nodes.

If all the nodes have been removed from the axilla, radiotherapy to this area is not usually needed.

Chemotherapy for breast cancer

Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells.

The aim of chemotherapy is to do the maximum damage to cancer cells while causing the minimum damage to healthy tissue.

Indications: Before surgery to shrink the cancer. This is

known as neo-adjuvant chemotherapy. After surgery if doctors think there is a risk of

the cancer coming back. This is known as adjuvant chemotherapy.

ChemotherapyThere are many different chemotherapy drugs used to treat

breast cancer, and they are often used in combinations (called a chemotherapy regimen).

The commonly used chemotherapy drugs include: cyclophosphamide epirubicin fluorouracil (5FU) methotrexate paclitaxel (Taxol) doxorubicin (Adriamycin®) docetaxel (Taxotere®).

Hormonal therapies for breast cancer

Hormonal therapies are treatments to reduce the levels of hormones in the body or block their effects on cancer cells.

They are often given after surgery, radiotherapy, and chemotherapy for breast cancer, to reduce the chance of recurrence.

Hormonal therapies are only effective in women whose cancer cells have receptors for oestrogen and/or progesterone on their surface.

This is known as being oestrogen-receptor positive (ER+) or progesterone-receptor positive (PR+).

Hormonal therapy for postmenopausal womenPostmenopausal women may be offered hormonal

treatment with either an anti-oestrogen (such as tamoxifen) or an aromatase inhibitor (such as Arimidex®).

Tamoxifen has been the most widely used hormonal therapy for breast cancer and has been shown to be highly effective in reducing the chance of the cancer coming back.

Research has shown that for some women, giving aromatase inhibitors instead of tamoxifen, or after a period of tamoxifen treatment, can further reduce the chance of the cancer coming back.

Hormonal therapy for premenopausal women

Premenopausal women may be offered hormonal treatment with: an anti-oestrogen drug (such as tamoxifen) Treatment to stop the ovaries from producing

oestrogen (ovarian ablation). This can be done using surgery, radiotherapy, or a drug called goserelin (Zoladex® ).

Unfortunately, ovarian ablation by surgery or radiotherapy brings on an early menopause, which can be very upsetting, especially for women who were hoping to have children. The effects of medicines are usually temporary.

Biological therapy - Herceptin® (trastuzumab) for breast cancer

Trastuzumab| ( Herceptin®) is a monoclonal antibody.

It works by attaching to HER2 receptors (proteins) on the surface of breast cancer cells.

This stops the cancer cells from dividing and growing. Herceptin can reduce the chance of breast cancer to

recur after initial treatment for early breast cancer. However, it is only effective for women whose breast

cancer cells have a large number of the HER2 receptors on their surface. This is known as being HER2-positive. Around 1 in 5 women (20%) with breast cancer are HER2-positive.

Biological therapy - Herceptin®Side effects are usually mild, but some women may

have: flu-like symptoms, diarrhoea , headaches , allergic reaction.

In some women, Herceptin may cause damage to the heart muscle, which could lead to heart failure.

If this happens the Herceptin® will be stopped. Usually, the effect on the heart is mild and reversible.
