What type of carcinoma typically does not require chemotherapy?

Basal cell carcinoma typically does not require chemotherapy because it is generally considered a non-aggressive form of skin cancer. This type of carcinoma is often localized and grows slowly, which allows for effective treatment through surgical excision or topical therapies. Chemotherapy is usually reserved for more aggressive forms of cancer or when metastasis has occurred, which is not common with basal cell carcinoma. The focus for treating this carcinoma is primarily on removal and ensuring it doesn't recur, rather than on systemic treatment measures such as chemotherapy.

Other types of carcinoma listed, such as squamous cell carcinoma, breast cancer, and lung cancer, often necessitate a more aggressive treatment approach, including chemotherapy, especially in advanced stages or when there is a risk of metastasis.
