Erin, welcome to OCF! Im very sorry your father has been diagnosed with OC. You will find lots of important info and support on this site.

Treatments are difficult for most patients. But it can be done. The key to making it easier is focusing on what is controllable... the patients intake. Every single day they need a minimum of 2500 calories and 48-64 oz of water. If they can take more in like 3000 or even 3500 calories that can only help make it easier. Many struggle with taking in enough water. Ask the doc for an open prescription to get hydrated a few times per week in the chemo lab. A couple bags of saline can help the patient feel much better right away.

Make a list of every single person (and their contact info) who offers to help. Tell them when the time comes you will give them a call. There are many little things that can add up to making a big difference in rough weeks of treatments. People generally are good and want to help but dont be surprised if some will not handle it well and they head for the hills until its over.

Read and learn from the ones who have come before you. There are thousands of posts to learn from and many important things on the main OCF pages.

Best wishes!
