Mitomycin C (MMC)
This is a chemotherapy drug that is applied to the surface of the tumour in theatre. MMC works by sticking the cancer cells’ DNA (the cell’s genetic code) together, stopping the tumour or cancer cells from growing.
This is applied to the surface of the cancer cells and therefore side effects of chemotherapy such as nausea, vomiting or hair loss are not experienced.
If MMC eye drops are being used, however, this can irritate the eye. We may give lubricant or steroid drops to treat this.
This treatment, also called imiquimod, is a chemotherapy drug which is applied to the surface of skin tumours. Sometimes we use this to treat eyelid tumours. This drug causes the body’s immune system to produce a chemical called interferon. This attacks and kills cancer cells. It may irritate the skin when applied, this means the treatment is working. It is applied 3 – 5 nights a week and treatment can last up to 6 weeks.
