How your immune system works might not be as strong as it was before cancer. Lots of cancer treatments make the immune system weak. Diet changes, stress, and sleep problems may as well impact your immune system. Having a weak immune system makes it harder for you to fight infections. It also makes you more likely to have a disease if you do become infected.


You can follow these safety measures to help lower your risk. Share these as well with other people you live with to do the same:

  • Stay at home as much as you can.
  • Keep at least 6 feet of space between yourself and other people.
  • Wear a face mask.
  • Avoid crowds when you do go out.
  • When sneezing or coughing, consider using a tissue or your elbow instead of your hand. Make sure to wash your hands after or even after you’ve been to public places. 
  • Wash your hands regularly.
  • If you can’t use water and soap, hand sanitizer is an option. Use the one that contains at least 60% alcohol. Rub it on all parts of your hands and let it air dry.
  • Try not to touch your mouth, nose, or eyes unless you’ve just washed your hands.
  • Clean all surfaces you touch a lot. Use regular household cleaning wipes or spray.


If you have your cancer treatment in the present, talk to your cancer treatment team about when you should call them and what you must watch for. Be sure you know how to reach them on weekends, on holidays, or after office hours. Also;

  • Stay away from anyone who appears to be sick.
  • Be extra careful about following the recommendations made by the local health authorities to help lower your risk of infection.
  • Make sure you have enough medication at home.
  • Make a list of emergency numbers that you might need so you have them all in one handy place, just in case.
