Pink mole thing on hip. Been there 2 years and hasn't changed. Smaller than an eraser. Doesn't bleed or itch. It becomes darker in sun. Is ok or bad?

Lesion hip 2 yrs. Let a doctor examine it and decide if a punch biopsy is needed.
OK. If worried, see a dermatologist. Do not become a recluse. Unless you are a vampire you should get out. Protect yourself from burning in the sun. Look for shade, especially in mid-day. Hat. Glasses. Clothing. Sunscreen.
Avoid sun. You should avoid sun exposure, especially to the mole. If it has not changed over two years, you can keep a watchful eye on it. If you notice any change, see your doctor for evaluation and may be excision and examination of the lesion by a pathologist.
