What is the hard painless lump at base of your neck?

The hard painless lump at the base of your neck is most likely a lipoma, which is a benign fatty tumor. Lipomas are usually soft, movable, and painless, and they can occur anywhere in the body. They are most common in adults between the ages of 40 and 60, and they are more common in men than in women.

Lipomas are caused by an overgrowth of fat cells. The exact cause of this overgrowth is unknown, but it is thought to be related to genetic factors and obesity. Lipomas are not cancerous, and they do not usually cause any problems. However, they can sometimes become large and unsightly, and they can cause pain or discomfort if they press on nerves or blood vessels.

If you are concerned about a lump in your neck, it is important to see a doctor to get it checked out. Your doctor can determine whether the lump is a lipoma or another type of tumor. If the lump is a lipoma, your doctor will likely recommend leaving it alone unless it becomes problematic. However, if the lipoma is large or causing symptoms, your doctor may recommend surgery to remove it.
