Hello and welcome to e health forum. â
Symptoms like persistent fever, weight loss, night sweats along with multiple enlarged, painless lymph âââânodes may indicate conditions like lymphoma or cancer. âBut it is less likely, that the lump can be a âcancer in your case, since you are young and might not be having such issues.â
The description of the lump and the location, indicates it to possibly a collection of fat tissue also called âa Lipoma. Other âpossible causes include a sebaceous cyst.
In case of lipoma, it can be excised with a small surgical procedure, OR in case of a cyst, it can be âreduced in size âwith a needle aspiration or removed completely by excising it.
You might consult with your doctor who can examine you and provide proper advice and treatment.
I hope this helps.â
