Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

What is Breast Cancer?

Breast cancer is the most common cancer in the United Kingdom. Every year 48,000 new cases are diagnosed there. Of these, 80% are over 50 but younger women, and in rare cases, men, can also get breast cancer. Breast cancer is the leading cause of death for women aged 34 to 54.

Mayo Clinic researchers discover how ovarian cancer may begin

Little is known about what causes ovarian cancer, and there is no way to detect it early yet. About 75% of the time when someone is diagnosed with ovarian cancer, it has already progressed to stage 3 or stage 4, which means it has spread to other parts of the body.

BRCA mutations sharply increase risk of implant-associated lymphoma

Women with breast cancer who were also carriers of the BRCA1 or BRCA2 mutation and received textured breast implants as part of their reconstructive surgery after mastectomy were 16 times more likely to develop breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a rare T-cell lymphoma, compared with similar women without these genetic mutations, according to a study published today in Blood Advances.
