Malignant tumors are a type of cancer. Malignant tumors are abnormal cells that grow and invade other tissues or organs. They may spread to other parts of the body through the lymphatic system or bloodstream. Malignant tumors are classified as carcinomas, sarcomas, lymphomas, and melanomas. Each type of malignant tumor has a different origin and presents different signs and symptoms.
What is a Carcinoma?
Carcinomas are the most common type of malignant tumor and are derived from epithelial tissue, which covers the surfaces and cavities of the body. Carcinomas can occur anywhere in the body and can form in the skin, lungs, breasts, pancreas, esophagus, and other organs. The most common type of carcinoma is lung cancer.
What is a Sarcoma?
Sarcomas are malignant tumors that arise in the supportive and connective tissue, such as fat, muscle, cartilage, bone, and other connective tissues. Sarcomas can occur in any part of the body, but they are most common in the arms and legs. The most common type of sarcoma is osteosarcoma, which affects the bones.
What is a Lymphoma?
Lymphomas are malignant tumors that develop in the lymphatic system, which is part of the immune system. Lymphomas can occur anywhere in the body but are most commonly found in the lymph nodes, spleen, and bone marrow. The most common type of lymphoma is Hodgkin lymphoma.
What is a Melanoma?
Melanomas are malignant tumors that arise from melanocytes, which are specialized cells in the skin that produce the pigment melanin. Melanomas can occur anywhere in the body, but they are most commonly found in the skin and can be identified by a dark, irregularly shaped mole. Melanomas can be life-threatening if not identified and treated early.
