Breast cancer is an abnormal growth of tissue in the breast also referred to as malignant. Malignant tumours are cancerous and can spread to other parts of the body. Males have a small amount of breast tissue, and although rare, can be affected by cancer. Breast cancer occurs in both men and women whereby less than 1% of all breast cancers occur in men.
