What are the chances of having cancer in lyph nodes in groin at 21 years old?

It depnds: Cancer is uncommon. Lymph glands can become cancerous due to lymphoma. But then they will progressively enlarge in size to over 2-3cm. If that is the case, then go get checked by your doctor.

Low: Almost all young people have palpable lymph nodes in the groin. Mine used to get bigger every summer from going barefoot in rural illinois. If one of them is malignant, it will be an obvious abnormality -- way to big, or rock-hard, or stuck to the surrounding structures.

Lymphoma: Lymphoma certainly increases with age, for example, from age 20 to 24 years, the rate of non-hodgkins l (nhl) is about 2.5 cases per 100, 000 population, from age 60 to 64 years, the rate increases to 44.6 cases per 100, 000 population, and from age 80 to 84 years, the rate increases to 119.7 cases per 100, 000 population. Most enlargement is due to infection or "reactive, " but see doc if need be.

Groin lymph nodes: Enlarged lymph nodes have numerous causes including cancer, infections and other diseases. You need evaluation by your primary care doctor and probably some tests.

Health: Nearly zero. Lymph nodes are a sign that your immune system is working; that it is healthy and doing what it is designed to do. Humans have no real idea how many bugs and other infectious things are around them at all times. Our immune system is active and working and if we can feel nodes then this is a sign we should welcome because it represents health.
