2 month old painless lump on upper eye lid. 2 ophthalmologists diagnosed chalazion. recently noticed eyelashes falling, 2nd ophthalmologist says there is no eyelash loss. scared that lump is sebaceous cancer but the doctors are missing it. i'm 26 yo.

Ask both eye Drs.: One can just ask both eye doctors about eyelid cancers. Eye doctors (ophthalmologists) are the specialists who can identify eyelid cancers. If both say the lump is not an eyelid cancer with a high level of certainty, then it is not an eyelid cancer, with a high degree of confidence. Of course, a patient would continue to follow-up with the eye doctor until the lump resolves over time.
