Proton therapy cannot be performed if the patient has a pacemaker. Patients with prostate cancer and metal hip prostheses also cannot receive proton beam therapy.
Proton therapy is not used to treat patients with the following diagnoses:
small cell carcinoma of the lung;
malignant neoplasms of the skin (eg melanoma);
cancer of the biliary tract, stomach, intestines;
cancer of the kidneys, bladder, genital organs;
some tumors of the central nervous system;
advanced cancer with multiple metastases.
If the treating oncologist strongly recommends proton therapy, then you can consult at the center: all doctors are qualified and experienced in the field of conventional radiotherapy and their opinion will be useful.
