Hmm.. Ive read about chemotherapy that can be taken orally. Meaning that its in the form of a pill, capsule or liquid. Maybe you can find out more about this form of chemotherapy or how effective it really is.
For chemotherapy through an iv, the only discomfort is caused when inserting the needle into the vein. After that, the treatment is painless. Different people have different tolenrance levels so maybe it doesn't even hurt!
Chemotherapy may also be done through a intraperitoneal (ip) port. According to a patient currently using this, it is just a relatively painless port, and it doesnt itch. It sits under the skin, in the fat layer and does not require any specific home care too. Blood tests and medication can be administered through the port. Although a needle has to be inserted into the port, it apparently is almost painless, and much more bearable compared to an iv.
Hope you find this helpful! (:
