Cancer Dictionary

Acute Lymphoblastic Leukemia (ALL) is a rare type of cancer characterized by the rapid production of abnormal white blood cells in the bone marrow. These cells impede the production of normal blood cells, triggering symptoms like fatigue, fever, and bleeding. ALL is most common in children but can also occur in adults. Treatment often involves chemotherapy, radiation, targeted therapy, or stem cell transplant.

Anal cancer is a rare type of malignancy arising from the anal canal or rectum. It starts when healthy cells in or around the anus change and grow out of control, forming a mass. Risk factors include increasing age, history of HPV infections, and smoking. Symptoms may include rectal bleeding, pain, or changes in bowel movements. Treatment often involves chemotherapy, radiation, or surgery.

Angiosarcoma is a rare, malignant tumor that originates from endothelial cells, the cells that line the interior surface of blood vessels. It can occur anywhere in the body, but is most commonly found in the skin, breast, liver, spleen, and deep tissue. Due to its aggressive nature, it often leads to a poor prognosis. This tumor presents unique challenges due to its high recurrence rate and resistance to treatment.
