Cancer Dictionary

Lobular carcinoma in situ (LCIS) is a condition that indicates the presence of abnormal cells in the lobules of the breast. Although not a cancer itself, LCIS is considered a marker for increased risk of developing breast cancer in the future. It's often detected during a biopsy for another breast condition or during a mammogram.

A lumpectomy is a surgical procedure performed to remove a discrete portion or "lump" of tissue, usually a breast tumor, from an afflicted individual. It is often employed as an effective treatment for early-stage cancer, retaining most of the breast tissue and offering a less invasive alternative to mastectomy.

Lung cancer is a type of malignant disease characterised by the uncontrolled growth of abnormal cells in one or both lungs, specifically in the tissues or air passages. It can be primarily caused by smoking, but non-smokers can get it too due to reasons like exposure to radon gas or secondhand smoke. It's often fatal due to late-stage diagnosis, making early detection crucial.

Lymph nodes are small, bean-shaped structures that act as filters for harmful substances and are essential to the immune system. They produce immune cells to fight infections and trap viruses, bacteria, and other causes of illnesses before they can infect other parts of the body.
