3. Hard, Yellowish Lumps on Eyelids
If you suddenly develop a hard yellow lump on your eyelid, have it checked out. These lumps may also appear on the head or neck, trunk, or genital area. These hard lumps can be a rare cancer, sebaceous gland carcinoma. They are slow growing and not particularly aggressive, however treating them is important!
These can be a clue that there is cancer elsewhere in the body (Muir Torré syndrome). They may also be benign (non-cancerous) and merely annoying.
