cancer occurs when cells begin to grow and multiply in an uncontrolled way.Normal body cells grow and divide over a period of time until they eventually die. But cancer cells continue to grow and divide and grow and divide. Eventually, they gather to form tumors
what is a tumor
you ask to many questions,but fine a tumor. tumors are lumps that can interfere with the body's normal processes. Sometimes cells from a tumor break away and travel to a different tissue or organ.
What is metastasis
last question ok. Metastasis is the medical term for cancer that spreads to a different part of the body from where it started. When this happens, doctors say the cancer has “metastasized.”
