Doppler Ultrasound Side Effects and Warnings

My 90 year old father has lymphoma in the left groin. After a vigorous ultrasound test for a local DVT he developed the following symptoms which he had never had before the ultrasound: swelling of the lymphoma, edema of right leg, temporary swelling of the penis, back pain, and incontinence. These effects occurred immediately post ultrasound; some have dissipated. During and after exhausting the conventional therapies (radiotherapy) we are giving him natural therapies to deal with the lymphoma, inflammation and general health (including getting the pH to be alkaline) and it is slowly having a positive, healing effect. This is his second lymphoma on this site in 8 years, a Lymphoma of Unknown Melanoma Primary (LUMP). The oncologists are astounded that he is still alive as he has wrecked their statistics (12% chance living up to 5 years). They said he should be dead or at least have metastatic tumours (none).
