Breast cancer. Section through breast tissue that was removed by mastectomy, showing a malignant phyllodes tumour. At right (pink) is the diseased cancerous tissue. Normal breast tissue is white at upper left, with a glandular appearance. The scale reference is in centimetres. The tumour size and spread prompted removal of the breast. Cancer of the breast is the most common cancer in women. In most instances the disease is diagnosed by mammo- graphy (X-ray) screening, or found as a smaller lump during self-examination. Surgical removal cures a third of women with early cancer; radical surgery has now been replaced by lumpectomy, combined with radiotherapy and anticancer drugs.
