syöpäkasvaimeksi

Syöpäkasvain, also known as a malignant tumor, is an abnormal growth of cells in the body that have the potential to invade surrounding tissues and spread to distant parts of the body, a process called metastasis. Unlike benign tumors, which are typically non-cancerous and do not spread, cancerous tumors are characterized by uncontrolled cell division and a failure of cells to undergo programmed cell death, or apoptosis. This leads to the formation of a mass of abnormal cells that can disrupt normal organ function.

The development of syöpäkasvain involves a series of genetic mutations that alter the normal behavior of cells. These mutations can arise spontaneously or be caused by environmental factors such as exposure to carcinogens like certain chemicals, radiation, or viruses. Once these mutations accumulate, cells can begin to grow and divide uncontrollably.

Symptoms associated with syöpäkasvain vary widely depending on the type and location of the tumor. General signs can include unexplained weight loss, persistent fatigue, a lump or thickening in any part of the body, changes in bowel or bladder habits, and unusual bleeding or discharge. Diagnosis typically involves medical imaging, blood tests, and a biopsy, where a sample of the abnormal tissue is examined under a microscope. Treatment strategies for syöpäkasvain are diverse and may include surgery to remove the tumor, chemotherapy, radiation therapy, immunotherapy, and targeted drug therapy, often used in combination. The prognosis depends on many factors, including the type of cancer, its stage, and the patient's overall health.
