repeated occurrences of blood blisters on palate of mouth

For the third time in the last 4 months, large blood blisters on the palate of my mouth (next to a tooth) have appeared. I was tempted to pop it the first time but didn't and it eventually went away. A second blister appeared on the other side of the palate near tooth. I accidentally pierced it with a fingernail and a lot of blood drained from my mouth. It too went away after a week or so. A third blister, in the same location as the first, has appeared and is starting to disappear again. Is this a sign of cancer or some sort of known disease?

Hello,
The symptoms are suggestive of pyogenic granuloma. Pyogenic granuloma commonly effects the oral mucosa and appears as an overgrowth of tissue to due irritation, physical trauma or hormonal factors. Some doctors prefer to treat with chemicals (TCA, podophyllin, phenol, silver nitrate). Laser surgery can also be done. Best treatment is however surgical excision. If it bleeds again then it may need treatement.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
