Yervoy (ipilimumab) is a medication used to treat certain types of cancer, including melanoma and advanced renal cell carcinoma [2]. It works by activating the immune system to attack cancer cells [2]. However, there are alternative medications available for the treatment of cancer.

One alternative medication is Opdivo (nivolumab), which is also an immunotherapy drug that works by blocking the PD-1 protein on cancer cells, which allows the immune system to recognize and attack cancer cells [2]. Opdivo is approved for the treatment of melanoma, lung cancer, kidney cancer, and other types of cancer [2].

Another alternative is Keytruda (pembrolizumab), which is also an immunotherapy drug that works by blocking the PD-1 protein on cancer cells, allowing the immune system to attack cancer cells [2]. Keytruda is approved for the treatment of melanoma, lung cancer, head and neck cancer, and other types of cancer [2].

Avelumab (Bavencio) is another alternative medication that is used to treat certain types of cancer, including Merkel cell carcinoma, urothelial carcinoma, and renal cell carcinoma [3]. It is an immunotherapy drug that works by blocking the PD-L1 protein on cancer cells, allowing the immune system to attack cancer cells [3].

In conclusion, there are several alternative medications available for the treatment of cancer, including Opdivo, Keytruda, and Avelumab. These medications work by activating or blocking certain proteins on cancer cells, allowing the immune system to recognize and attack cancer cells. It is important to discuss treatment options with a healthcare provider to determine the best course of action for each individual case.
