I was bitten on the side of my neck by an unknown insect (not a mosquito) in South Africa one year ago. The bite never completely healed and recurrently got inflamed with itching and bleeding. For an entire year the site was inflamed and irritated with episodic bleeding.My dermatologist finally decided to excise it surgically. The biopsy showed basel cell carcinoma. Could the chronic inflammation of this bug bite that never healed have caused the carcinoma, or was this just a coincidence? Can chronic (one year) inflamation that resulted from the bug bite could have caused the cancer. Or was it a complete coincidence that I developed a basal cell cancer at the exact same (non sun-exposed) site where the bug bite occurred.
