Malignant lesion
Malignant Lesion
A malignant lesion is a term used in medicine to describe an abnormal growth that is harmful and can spread to other parts of the body. This is in contrast to a benign lesion, which is a non-cancerous growth that does not spread. Malignant lesions are often associated with cancer and can occur in various parts of the body.
Types of Malignant Lesions[edit | edit source]
There are several types of malignant lesions, including:
- Carcinoma: This is the most common type of cancer and originates from the skin or tissues that line the internal organs.
- Sarcoma: This type of malignant lesion develops in the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
- Leukemia: This type of cancer starts in the blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.
- Lymphoma and Myeloma: These cancers begin in the cells of the immune system.
Diagnosis[edit | edit source]
The diagnosis of a malignant lesion often involves a series of tests, including biopsy, imaging tests, and laboratory tests. A biopsy involves removing a small sample of tissue for examination under a microscope. Imaging tests, such as X-ray, CT scan, MRI, and PET scan, can help determine the location and size of the cancer. Laboratory tests, such as blood tests, can help detect certain types of cancer.
Treatment[edit | edit source]
Treatment for malignant lesions depends on the type of cancer, its stage, and the patient's overall health. Options may include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, hormone therapy, stem cell transplant, or a combination of these. The goal of treatment is to kill or slow the growth of cancer cells while minimizing side effects.
