What is breast cancer?

Our cells sometimes grow old and become damaged. These are called malignant cells. When these malignant cells multiply repeatedly, a cancerous lump or tumour may form. These cells may spread to the rest of the body if left untreated. Although breast cancer mainly occurs in women, men can sometimes get breast cancer. This is rare though. Although more women today are being diagnosed with breast cancer than in recent years, more women are surviving breast cancer than ever before as well.
