Breast cancer is the most common cancer in women in the UK. A breast lump is the first symptom in 9 out of 10 breast cancers. Breast cancer can also affect men.
Treatment for breast cancer may include a combination of surgery, radiotherapy, chemotherapy, drugs to block hormones or their effects on cancer cells (hormonal therapies), and a drug called Herceptin® (trastuzumab).
The type of treatment you have will depend on many factors, including the size of the tumour and whether you have had your menopause.
