when the cold was gone this lump came

Hello and thank you for posting your health query on E health Forum.‎

Your lump described could be due to a enlarged lymphnode.

At a young age of 24, it is very unlikely that you can have a cancer.

Lymph node enlargement is a very common sign and can cause many people to get stressed and ‎lose their sleep. A few major symptoms and danger signs can help you differentiate very common ‎benign conditions from those indicating conditions like cancer and chronic diseases. ‎

Symptoms like persistent fever, weight loss, night sweats along with multiple enlarged, painless ‎lymph nodes may indicate conditions like lymphoma or cancer.‎

Smaller single nodes, that are tender to pressure without any other signs mentioned above can ‎signify many common conditions including including upper respiratory tract infections, chronic ‎infections like tuberculosis, local asymptomatic skin infections, etc.‎

The presence of small lymph nodes under the jaw and the throat, for a long time, may indicate a ‎underlying chronic infection in the naso-pharyngeal-respiratory tract.

You might consult a doctor and undergo investigations, including a biopsy of the lump, which might help to diagnose the cause of the lump.

I hope this helps
