3 What is Breast Cancer?
As the name suggests, it is a cancer that affects the
breasts or mammary glands. In technical terms it
is a carcinoma of the breast which is either ductal
or lobular. It is a breast malignancy which is more
prominent in females than males and is the second
most frequent cause of cancer death.
The etiology is complex as there are different risk
factors involved. Risk of breast cancer is higher in
women above the age of 50 with an early detection
and change in lifestyle, it can be controlled.

4 Breast Cancer Facts
Breast cancer is 100 times more frequent in women in comparison to men.
Prognosis is the same in both.
Most common cancer in women - the incidence rate among females is twice as much as that of
colorectal cancer and cervical cancer and approximately three times that of lung cancer.
Globally, the incidence of breast cancer is the highest among American women.
About 16% of women between the age of 40-60 years have breast-related problems. Of these
40% complain of breast lumps.
In women over 40 years, these breast lumps may carry a risk of breast cancer.
However, the majority of these breast- related complaints may be due to benign breast disease.

Personal and family history of breast cancer
Late parity
Early age menstruation & late menopause

9 Staging / classification
In today’s date the TNM (Tumor, Nodes, Metastases) Classification is recognized and accepted worldwide
which takes into consideration the tumour itself, the involvement of the lymph nodes and the metastasis
to other body parts. The prognosis and treatment which suits best to the patient is closely connected to
the stage of the tumour.
STAGE - 0
Cancerous cells are in their original location within the
breast tissue.
STAGE - I
Tumour less than 2cm in diameter with no
enlargement beyond the breast.
10. Trivia on Breast Cancer www.sastasundar.com
10 Staging / classification
STAGE - II
Tumour within 2-5cm in size without spreading to the
lymph nodes of axilla, or else tumour less than 2cm
spread beyond to the axillary lymph nodes.
STAGE - III
Tumour smaller than 5cm disseminated to axillary
lymph nodes which are attached to each other or to
other structures.
STAGE - IV
Tumour of any size which spreads to other organs
beyond the region of the breast and chest wall such
as liver, lungs or bone.
11. Trivia on Breast Cancer www.sastasundar.com
11 diagnosis
The identification of this disease can be done by examining the symptoms in the following ways -
Clinical Breast Examination - A self breast examination can be done or else a thorough clinical exam which can
reveal any lump if formed.
Mammograms - A low radiation X-Ray therapy used to detect breast cancer prior to the appearance of symptoms.
Ultrasonography - Reveals if the lump is fluid filled cyst(not cancer) or a solid mass(might or might not be cancer).
Magnetic Resonance Imaging (MRI) - Defines the size & extent of cancer within the breast tissue.
Digital Mammography - Similar to standard mammography but advantageous of digital storage of images
& enhancement by brightness & contrast modification.
Biopsy - Done to collect a tissue sample to be examined under the microscope.
Fine Needle Aspiration - Fluid and/or cells removed from a breast lump using a thin needle.
Needle Biopsy - Tissue removal using a needle from a suspicious area on a mammogram which can’t be felt.
Stereotactic Needle Biopsy - uses a mammogram directed technique to map the exact location of the breast lump.
Surgical Biopsy - Cutting out a sample or all of a lump of a suspicious area.

12 prevention
May how appalling this disease be, there are certain preventive measures proposed to keep breast
cancer at bay.
breast examination
Self breast examination helps to detect breast cancer early. It leads you to
see a doctor.
Health Check-up
An annual Health Check up every year by a medical professional for
women above 40 years and every three years for women between 20-39
years to enable early detection.
Avoid Alcohol
Avoid alcohol. Drink in moderation. If it is not possible then one should quit
consuming alcohol.
13. Trivia on Breast Cancer www.sastasundar.com
13 prevention
Regular exercise
Exercise everyday for a minimum of 30 minutes.
say no to obesity
Control weight gain as obesity is a high risk factor for breast cancer.
risk factor
Reduce the intake of HORMONE REPLACEMENT THERAPY (HRT) drugs as they
increase the risk of breast cancer.
high risk group
For those in the high risk group, preventive medications (oestrogen blocking)
& preventive mastectomy are sensible options.
14. Trivia on Breast Cancer www.sastasundar.com
14 treatment
There are 3 trails that can be followed after the triple diagnosis -
»
Women in whom the triple diagnosis suggests benign disease are closely monitored (physical
examination every 3 to 6 months for at least a year) to ensure that the breast mass is stable.
Women in whom the diagnosis suggest malignancy are referred for treatment.
Women in whom any one of the triple tests suggests malignancy need to undergo excisional biopsy.
»»
The choice of treatment depends on factors like the extent to which the cancer has spread, characteristics of the
cancer & physical condition of the patient.
The two common options are surgery and therapy.
The main mode of treatment for breast cancer, especially so when the tumour is localized is surgery. It must be
noted that even through breast cancer is of the breast, the cancer can spread to other body parts which is why
breast cancer’s treatment almost always involves surgery.

The different types of surgery are –

A surgery is often followed up by other treatments to be mentioned below which depends on the risk
status of the patient’s cancer – high or low risk. Factors like, the patient’s age, type and size of cancer,
metastasis of the disease decides the risk status of the patient.
