Radiation therapy benefits after negative Biopsy and zero cancer
My mother at age 79+ had growth in neck in Dec 2020 and. She underwent surgery to remove the growth in neck and the biopsy confirmed Head & Neck cancer with unknown primary source in April 2021.
She continued her Ayurveda treatment along with meditation, massages for Amma (cancer indicates Tamas) and some cow urine treatment for 1 month.
They had to remove small amount of tissue once again in Sept 2021, due to infection and biopsy report for cancer came negative. PET CT Scan had shown some suspicion of fast absoption of nutrition there.
Now the doctors were a bit doubtful about the need for RT but then after my sister asking second time, agreed and suggested RT for 30 visits.
Mother is reporting quite a bit of difficulty swallowing, feeling very weak and drained after 4 days of RT already. She is continuing powerful meditations.
Is there any particular need or benefit of RT besides general precautionary step to avoid recurrence of cancer? Some cells will lurk around obviously but body can also heal itself usually (from what I read its common.)
