My mom has cancer and has gone through 5 rounds of chemo at the MD Anderson Cancer Center. Her doctor wants to do radiation in conjunction with her next round. We all, including my mom, live in Florida so this would require lodging in Houston where the cancer center is. The radiation treatments are tentatively for 4-6 weeks. So all of us would need to stay in the same place. My mom does have other family that could stay with her but I am just wondering if my 20-month old can be in the same house with someone doing radiation. Is there a risk? Thank you for your time.
