Mothers, aunts, sisters, daughters—the effects of breast cancer on people’s lives spread far. If you have not been personally affected by the disease, chances are you know someone who has.

During Breast Cancer Awareness Month this October, people across the country will be opening up their wallets to send a donation to thousands of organizations with a host of different goals: cancer research, financial assistance with medical expenses, and education, among others.

If you’re trying to decide just where you’d like to give your donation, Promise Local will help you connect with the nonprofits putting in the hard work.

Promise Local is bridging the gap between generous donors and the worthy nonprofits who are spending your donations most efficiently. Promise Local takes the research and guesswork out of the donation process and connects you with the nonprofits making a difference in your communities and across the nation.

Supporting these reputable nonprofit organizations ensures that most of your donations are going directly to the cause.

Since its founding, no other nonprofit organization has generated more funding for breast cancer research than the Susan G. Komen Breast Cancer Foundation. Komen’s donations also go toward breast cancer treatment and patient support. Living Beyond Breast Cancer is dedicated to providing breast cancer patients with the proper educational resources so they aren’t left feeling alone on their journey to recovery. The American Cancer Society funds cutting-edge cancer research and ensures that patients have accurate information about all of the possible treatment options.

For transparency and reliability, donate to one of these national organizations during Breast Cancer Awareness Month.
