Q. Do tumors always end up as cancer?
Doctor Answer is medically reviewed by SecondMedic medical review team.
No, not all tumors end up as cancer. Tumors can be benign (non-cancerous) or malignant (cancerous). Benign tumors tend to grow slowly and do not spread to other parts of the body, while malignant tumors can grow rapidly and spread to other organs in the body.
The best way to determine if a tumor is cancerous or benign is through a biopsy. Biopsies involve taking samples from the tumor tissue and sending it for laboratory analysis by a pathologist who will then diagnose whether there are any cancer cells present in the tissue sample. If it is determined that the tumor is malignant, further testing may be necessary for staging and grading of the tumor so doctors can choose an appropriate treatment plan.
It's important to know that not all cancers always require aggressive treatment such as surgery, radiation therapy or chemotherapy--in fact some forms of early stage breast cancer have been found to have no additional benefit with these therapies compared with active surveillance alone. Treatment options vary amongst different types of cancers, so it's always best to talk with your medical team about what option would be most appropriate depending on your particular situation.
