The most common symptom of breast cancer is a new lump or mass. But many women have breast lumps and 90% are benign, that is, they are not cancers. A painless, hard mass that has irregular edges is more likely to be cancerous, but breast cancers can be tender, soft, or rounded. They can even be painful. For this reason, it is important to have any new breast mass or lump or breast change checked by a professional health care experienced in diagnosing breast diseases.

Other possible signs of breast cancer include:

1. Swelling of all or part of a breast (even if no distinct lump is felt)

2. Skin irritation or dimpling

3. Breast or nipple pain

4. Nipple retraction (turning inward)

5. Redness, scaliness, or thickening of the nipple or breast skin

6. Nipple discharge (other than breast milk)

Sometimes a breast cancer can spread to lymph nodes under the arm or around the collar bone and cause a lump or swelling there, even before the original tumor in the breast tissue is large enough to be felt. Swollen lymph nodes should also be reported to your doctor.

Although any of these symptoms can be caused by things other than breast cancer, if you have them, they should be reported to your doctor so that he or she can find the cause.

*Surgery, in addition to the appropriate chemotherapy and radiotherapy, are effective in treating early cancer, but certain patients in late stage of cancer may not be tolerate surgery well as they can be relatively weak. A combination of carefully planned minimally invasive therapy, chemotherapy or radiotherapy can effectively reduce the side effects and discomfort of treatment and may help patient get better efficacy.
