7. Unusual lumps
Some experts say that in more rare and severe cases, unusual bumps, lumps, or swelling can be a sign that there is something that needs to be treated beneath the skin. Bumps that are linked to cancer are usually hard, large, and painless to the touch. However, they appear spontaneously and might grow in size in just a matter of weeks or months.
If you have any masses or lumps and you have no idea how you ended up with them, call your health care provider. Lymph nodes typically get swollen when you have a cold, but if the swelling is still there even after you’ve been well for quite a while, the best thing you could be doing is talking to a doctor.
