What's the Difference Between Benign and Malignant Tumors? A Summary of Tumors, Cancer and Treatment

Tumors result from tissue overgrowth, often due to DNA damage from radiation, tobacco, or environmental factors, leading to uncontrolled cell division. If large enough, tumors can damage organs or metastasize to other body parts.

Stem cells are thought to trigger tumor growth and can resist treatments like chemotherapy, allowing cancer to return stronger after initial differentiated cells are wiped out.

Chemotherapy originated from mustard gas and works by stopping cell growth, but has severe side effects like hair loss and immune suppression. Radiation therapy uses beams to damage tumor DNA, with minimal immediate side effects but potential long-term damage, and neither is 100% effective.

New research explores using a reengineered polio virus to attack brain tumors by weakening their defenses and enabling the immune system to fight. Another experimental treatment involves 'Tumor Paint' made from scorpion venom, which binds to brain tumor cells and glows under fluorescent light, aiding surgeons in identifying tumor margins.

It's important to be cautious and maintain a balance of optimism and skepticism regarding new experimental treatments for cancer, emphasizing that more research is always needed.

Not all tumors are cancer. Tumors, also called neoplasms, are categorized as benign (non-spreading) or malignant (cancerous and can spread).

Tumor names often indicate their origin. Examples include Adenomas (epithelial tissue), Fibroids (fibrous tissue, like skin tags), and Hemangiomas (collections of blood cells, like strawberry birthmarks).

Cancerous tumors include Carcinomas (epithelial cells), Sarcomas (connective tissue), Leukemia (marrow and blood/lymph nodes), and Blastomas (embryonic tissue).
