Early breast cancer usually does not cause pain. In fact, when breast cancer first develops, there may be no symptoms at all. But as the cancer grows, it can cause changes that women should watch for. It is either diagnosed by feeling a breast lump or finding an abnormality on mammography. A lump in the armpit or above the collarbone that does not go away may be a sign of cancer. Other possible signs are breast discharge, nipple inversion, or changes in the skin overlying the breast.

• Most breast lumps are not cancerous. Yet all breast lumps need to be evaluated by a doctor.
• Breast discharge is a common problem and is rarely a symptom of cancer. Discharge is most concerning if it is from only one breast or if it is bloody. In any case, breast discharge needs evaluation.
• Nipple inversion is a common variant of normal nipples, but nipple retraction as a new development can be a cause for concern.
• Changes in the skin of the breast include redness, changes in texture, and puckering. These changes are usually caused by skin diseases, but occasionally, can be associated with breast cancer.

For an early detection

• Breast examination should be done monthly after 20 years
• Clinical breast examination and mammography should be done annually after 40 years
