Kelp and vomiting

I developed salivary gland cysts from eating lemons.
I suffered from chronic pain. lost my period, and developed ovarian cancer. I turned to Sea Salt and got my saliva back and started eating kelp but now have stopped from vomiting acid every morning. I believe citrus and vitamin c is the true cause of cancer. I live with the pain everyday. I think kelp is good but the salt may be damaging to the heart.
