how much radiation cycles necessary?

Initially before starting chemo my sister was informed 4 weekly cycles by linac radiation will be sufficient. Now it is being informed by the doctors that 6 weekly cycles will be required. Is there any reason for this increase. I have asked the doctor the reason but not received any justification to my answer.

Doctor pl help the base or guidelines for the cycles. Why the increase is suggested?

  • The radiation always lasts for 6 to 7 weeks. There is no 4 weekly radiation. I guess there must have been some miscommunication.

    So don't worry. It's not that they have increased. RT is always 6 to 7 weeks.

  • Thanks doctor
