Yes, radiotherapy can cause hair loss, but you will usually notice this only in the area receiving treatment. For example, one clinical study found that 100% of patients with primary brain tumors experienced some degree of hair loss after radiotherapy, ranging from mild to more severe loss. Unlike chemotherapy, which often leads to widespread and temporary hair loss, radiotherapy causes hair loss that is localized and may become permanent if the dose is high. You may find that hair begins to thin or fall out in the targeted region, while the rest of your hair remains unaffected.

CT Simulation is a crucial step in radiation therapy. It ensures accurate treatment by mapping the precise location of cancer cells. Without proper preparation, the accuracy of radiation delivery can be compromised, which could affect the treatment's effectiveness.
