If you are the kind of person who would gladly offer to make a meal or run errands for a family facing childhood cancer, but don’t know any personally, it can be difficult to know what else you can do to help. Read below for three simple ways you can help a child with cancer, even if you never meet them.

Give blood. Children going through cancer treatment often need blood transfusions, and many hospitals struggle to obtain enough blood for these necessary procedures. You can help lessen this problem by giving blood, or even better, getting a group of friends or co-workers to all give blood together.

Donate your hair. This is a wonderful, selfless way to show your love for children who have lost their hair to chemotherapy. Your local salon may be able to direct you to organizations where you can donate hair and let you know how long it should be before you make the cut.

Spread awareness. Because childhood cancer is so rare, there are probably people in your life who don’t know anything about it. You can spread awareness about childhood cancer through face-to-face conversation, social media or other channels – and be sure to let people know they have the power to help, too!
