Welcome to OCF, Michelle! Im sorry to hear about your fathers recent diagnosis! You're in the best place for help from people who have been thru it. We''ll do our very best to support you and your father with up to date, correct info.
As far as doctors go, you may want to call your fathers insurance company. They would have a list of doctors for every specialty you are looking for. A doctor referral site may also be a resource for finding your father doctors. At OCF, our members are patients/survivors and caregivers without medical backgrounds so we are not qualified to rate physicians. Im pretty sure every patient/survivor on here if asked would rate their own doc as "the best". Instead of focusing on one specific doctor, it may be a good idea to look for a cancer treatment facility. At a Comprehensive Cancer Center (CCC) is where you should find the top doctors who all work together using a team based approach so everyone is on the same page. At a CCC the doctors all get together and discuss each individual case at whats called a tumor board meeting. Patients and caregivers are able to attend too. Im not completely certain but I think Mass General is a CCC. In the US, the top CCCs for oral cancer are Sloan Kettering, Moffitt, MD Anderson.
Ive added some links to help you at the end of this post. Read and learn about oral cancer (OC) so you can be a strong advocate for your father. OC is a horrible sickness to have. OC and treatments for it can be hard on patients. Since you've found us dont worry, we will help get you and your father thru whatever he faces.
As you share the bad news of your fathers cancer with friends, loved ones and co-workers, many will offer to help. People are genuinely good and you definitely will need help to get thru everything. Its a good idea to take down everyone who offers contact info and begin your list of helpers. Hopefully you will have someone who can be his caregiver. Anyone who has offered to help, take them up on it. Even if its just to drive your father to his treatment one day a week, its a help. There are a million small things that can be done to make this as easy as it can get. Dont be afraid to speak up and ask for help! Anyone who asks what they can do, they really want to help so if you need a hand give them a job. Take out the trash, do a load of laundry, walk the dog, mow the grass, pick up children or even playdates so you can get a break (of course that is if you have children), picking up groceries or cooking your family a meal are all small things that add up to making your life easier in this difficult time.
Best thing you can tell your father to help him at this point is to eat. He should have all his favorites, desserts too! Dont worry about calories or gaining a few pounds. During your upcoming treatments he will probably be like most of us and lose weight. If he's on the average or slim side having a few extra pounds going into this is a smart thing to do. Once your father starts treatments (if he does radiation... most of us unfortunately do end up doing rads), he will need to focus on his intake as much as possible. The better he does with his intake, the easier things will be for him. I cant stress enough how important it is to not lose any weight which can be very difficult to do. Patients weight loss is an early indicator of patients who are starting to struggle. During rads (if rads are part of his treatment plan), patients need at the very least 2500 calories per day and 48-64 oz of water. A patients intake is one of the most important things to focus on in order to get thru everything as easy as possible. I dont want to go too far ahead of myself but intake is a huge part of going thru cancer treatment of any kind so the sooner your father begins to watch his intake closely the easier it will be to do later when he is being treated.
Stick with us and we will do our best to answer your questions and help guide you and your father thru the treatment and recovery phases. It can be a long road but you arent alone, we are here to lean on. Hope I didnt overwhelm you with too much info. Best wishes to you both!!!
