In majority of women, breast cancer is first noticed as a lump in the breast. There are however, other signs and symptoms which are important.
- Change in shape or size of the breast
- Change in appearance of the skin in a particular area of the breast
- Dimpling or puckering of the skin on the breast
- A lump or thickening inside the breast
- Discharge from the nipple
- Rash on the nipple or surrounding area
- Inversion or turning in of the nipple
- Swelling of the upper arm

All women are at risk of developing breast cancer. There are a number of factors that put some women at a greater risk. These are:
- Women whose mothers, aunts or sisters have had breast cancer, have an increased risk of developing breast cancer.
- Chances of developing breast cancer increase as women grow older
- Women who have already had breast cancer have a slightly higher chance of developing cancer in the other breast.
- Early onset of periods (before the age of 12).
- Late menopause (after the age of 50).
- Women who have never had children and those who delay giving birth until they are over 30 as well as women who do not breastfeed

- Men can rarely develop breast cancer.
Being familiar with your breasts is in the interest of good health.
It is important to know how your breasts normally look and feel, so that you can detect new changes. If you notice any change in your breast appearance or consistency, you should report it to a healthcare provider right away.
If you become pregnant, you should still check your breasts regularly. Changes in size and tenderness of breasts are quite normal during pregnancy, but it is important to inform your doctor if you feel unusual changes in the breasts especially a lump, skin thickening or puckering.
What should you look for?
- Changes in the size, outline or shape of the breast causing flattening of the skin.
- Dimpling, creasing or puckering of the skin.
- A change in direction of the nipple or if it has started to draw in.
- Nipple discharge (some women produce a clear or milky discharge which is normal for them).
- New veins which stand out, particularly on one breast and not the other.
- Any skin changes on the breast or nipple.
What should you feel for?
- Any areas of thickening.
- Any lumps whatever their shape or form.
- Any lumpy areas.
- New or persistent pain or tenderness within the breasts.
Any changes you find that are new for you, must be checked by your doctor.
When to report to a healthcare provider?
- Appearance: any change in shape or outline/skin puckering
- Feel: any pain or discomfort in breast
- Any lump
- Any change in Nipple.
Mammography is a special x-ray of the breast which gives more information about the lump.
Screening mammography is the key for early detection as a it can pick up very small tumors, even before they can be felt. Diagnosing breast cancer at an early stage can help start treatment early and reduce deaths from breast cancer.
Start annual screening mammogram at 40 years of age. Continue as long as a woman is in good health.
