My father was previously diagnosed with stage 1 lung cancer and went for chemotherapy and was in remission successfully. However he continued smoking heavily and 2 years later, was diagnosed with stage 3 lung cancer. His doctor is suggesting using a mix of chemotherapy and proton therapy to treat the cancer. My father also has scarring on his lungs. Do you think it is a good idea for us to pursue the chemotherapy and proton therapy path? I saw my father losing weight rapidly previously from the chemo. Can we just do proton therapy?
Hi, it sounds like your dad’s disease has progressed. Usually, a formal re staging imaging using PET scans would be done to determine the stage of the disease. If the disease remains curable which from your query it is, then chemoradiation would be the choice of treatment over radiation alone. Before deciding on radiation treatment, usually an assessment of your dad’s lung function (especially if he is a smoker) would be required to determine his fitness for radiation. Whether your dad would benefit clinically from proton or normal radiation treatment, I would need to see him and review his imaging scans. Thanks
My husband has sarcoma and is now undergoing radiation therapy. He mentioned since the therapy started, his feet keep tingling and it affects his walking. Is this normal?
Hi, it is unusual for the radiotherapy to cause significant tingling that affects his walking. I would advise him to check with his doctor. Thanks
My husband is scheduled to have radiation therapy for his lymphoma. I have heard that radiation therapy has risks for pregnant women. I am now 4 months old pregnant. Should I keep a distance from him for a while? At the same time, I want to support him and accompany him for his doctor visits. Do you have any advice for me?
Hi, as your husband is undergoing external beam radiotherapy (EBRT), it is safe for you to accompany him for his treatment. There is no radioactive source being placed or Injected into him for EBRT treatment.
As long as you do not go into the radiation treatment bunker, you should be safe to accompany him for treatment.
If your husband is having a PET CT scan, where a radioactive tracer is injected into the body, then you should keep a distance from him for a while as he is potentially “radioactive”.
My husband has stage 3 lung cancer. Would radiation therapy help him at this point considering his stage of cancer? What is the success rate of treating his cancer with radiation therapy combined with chemotherapy?

My husband has been diagnosed with stage 1 throat cancer and his doctor has gotten him on 30 fractions of VMAT radiotherapy over a 6 week period. Does this sound suitable? I am worried about the side effects for him.
I assume that this is laryngeal carcinoma that you are talking about?
Or is it oropharyngeal carcinoma?
Is this pre or post surgery?
Is radiotherapy safe for children? My son is 6 years old and he has a brain tumor. I am worried it will harm his brain function.
For childhood brain cancers, treatment usually follows a protocol, usually either the COG protocols (USA) or the SIOP protocols (European). Most protocols usually involve a combination of modalities such as surgery, chemotherapy and radiotherapy, depending on the type of tumor. Radiotherapy usually have acute as well as late side effects – depending on the radiation dose, irradiated volume, location of the treated area and age of patient at the time of radiation. It would be best to discuss such late effects with a radiation oncologist specialising in pediatric cancers.
I heard that a combination of lumpectomy with radiation therapy is the best way to prevent breast cancer from returning. Is that true? What are the chances of stopping the relapse with this combination? How soon should the radiotherapy start after lumpectomy?
Hi, it is true that for patients who have chosen breast lumpectomy, radiation therapy post surgery is an important treatment in preventing breast recurrence. Numerous clinical trials have shown that in women undergoing adjuvant radiotherapy after lumpectomy, the relative risk reduction is about 60-70% compared to lumpectomy at 5 years. For patients who do not undergo chemotherapy, radiation usually commences about 2-4 weeks postop once the wound is healed. For patients who have to undergo chemotherapy, radiation usually commences about 3-4 weeks after the last cycle of chemotherapy.
My father was diagnosed with stage 2 non-small cell lung cancer. He was considered unfit for surgery due to his stroke history. Is radiotherapy a solution for him? Are there any risks we should be aware of if we decide to go with it?
For patients who are medically unsuitable for surgery, radiotherapy can be used as an alternative. Side effects of the radiotherapy will depend on factors such as your dad’s current condition and his current lung function, whether he was a smoker, the intent of treatment, site and volume of the tumor irradiated and the dose / fractionation of the treatment schedule. Would be best to discuss this with your doctor.
I am a 42 year old woman who has been diagnosed with skin cancer. My oncologist brought up radiotherapy. However, I am worried this would have a side effect on my face. I have sensitive skin and have been undergoing acne treatment since my teens and into my 30s. Would radiotherapy make my skin worse?
As an alternative to surgery, for certain types of skin cancers and depending on where the skin tumor is on the face, radiotherapy can be used. Side effects of treatment can include skin redness and pigmentation, which usually are temporary. Given your history of sensitive skin, it would be best to talk to your doctor about it.
