Breast cancer is the most common cancer among women and is the second leading cause of cancer deaths among women, according to the Centers for Disease Control and Prevention.

One way to help fight this devastating disease is to contribute to charities that focus on the research, prevention and treatment of breast cancer. But with the large number of organizations with similar names devoted to the cause, how do you know which ones are the best?

The first thing you should do when considering donating is to check with charity watchdog groups that evaluate how well each organization spends the money it receives from contributors.

Two of the biggest charity watchdogs are Charity Watch and Charity Navigator. Both groups evaluate thousands of charities and non-profit organizations by looking at financial statements, tax reports, program expenses and fundraising costs.

When giving to a charity it is important to consider three things, according to Charity Navigator CEO Michael Thatcher: Be clear on your motivation for giving and focus on where you want to make an impact, check the financial health and accountability of the organization, and check for signs of results.

In terms of breast cancer, consider whether you want your money to go for research and finding a cure, support services for cancer patients, helping support families or education and public awareness, Thatcher said.

CHARITY WATCH: TOP BREAST CANCER CHARITIES

The American Institute of Philanthropy’s Charity Watch cites 12 organizations as the top-rated cancer charities and of those there are three on the list that focus specifically on breast cancer prevention and research:

Breast Cancer Research Foundation

Mission: To prevent and cure breast cancer by advancing the world’s most promising research.

Program percentage (percentage of its cash budget it spends on programs relative to overhead): 90%
Cost to raise $100 (How many dollars a charity spends on fundraising to raise each $100 of contributions): $7

National Breast Cancer Coalition Fund

Charity Watch also gives top ratings to these broader cancer organizations on the list that are also involved in breast cancer research, treatment and education: Cancer Research Institute, Memorial Sloan Kettering Cancer Center, Prevent Cancer Foundation and the Entertainment Industry Foundation’s Stand Up To Cancer.

CHARITY NAVIGATOR: TOP BREAST CANCER CHARITIES

Charity Navigator uses a star rating system when evaluating how efficiently a charity uses your donations.

Of the three charities highly recommended by Charity Watch, the Breast Cancer Research Foundation received Charity Navigator’s highest rating of four stars. The National Breast Cancer Coalition Fund and the Breast Cancer Prevention Partners both received three stars.

Other national charities devoted to breast cancer research and medical services that received four stars from Charity Navigator:

National Breast Cancer Foundation
Mission: To help women now by providing help and inspiring hope to those affected by breast cancer through early detection, education and support services.
Score (out of 100): 96.0
Program expenses (Percent of charity’s total expenses spent on programs, services): 82.9%

Dr. Susan Love Research Foundation

Mission: To achieve a future without breast cancer and improve the lives of people impacted by it now through education and advocacy.
Score: 92.0
Program expenses: 81.9%

Lynn Sage Cancer Research Foundation

Mission: Funding life-changing breakthroughs in breast cancer.
Score (out of 100): 90.9
Program expenses: 92.1%

Charity Navigator also gave four stars to these charities that provide breast cancer support services and education: Bay Area Cancer Connections, It’s the Journey, Casting for Recovery, Sharsheret, BreastCancer.org, Prevent Cancer Foundation, Living Beyond Breast Cancer and American Italian Cancer Foundation.

Susan G. Komen

One of the largest and most well-known charities devoted to the cause is the Susan G. Komen breast cancer organization. The charity was founded in 1982 and was one of the first to devote itself to the cause of breast cancer research and has raised millions.

The organization’s reputation was damaged slightly after a decision in 2012 to cut its grants that funded breast cancer screening and outreach programs at Planned Parenthood erupted into controversy. The group quickly reversed its decision.

The organization also has received criticism for what some deemed excessive executive compensation and for “pinkwashing”—  cause marketing with pink ribbons that allow companies to exploit the disease for profit.

The charity received mixed scores from the watchdogs. Charity Navigator gives Susan G. Komen for the Cure a 3-star rating (out of four) and lists the percent of its expenses spent on programs and services at 81.6%.

Charity Watch gives the Susan G. Komen Breast Cancer Foundation a C+ rating with program percentage of 62%-77% and the cost to raise $100 of $12-$27.

DON’T GIVE: LOW-RATED CHARITIES

Charity Navigator also cites these organizations as being low-rated and states: “We caution you to look carefully before supporting one of these charities.”

A high concern advisory was issued for the defunct charities Breast Cancer Society and the Cancer Fund of America. The Federal Trade Commission ordered the organizations to be dissolved after alleging they were scam charities and bilked donors.

Other organizations rate lower because they scored lower on financial support and are spending more on fundraising than devoting funds to the issues, Thatcher said. “The money is going to spending money to make money.”

These organizations received zero or one star: National Cancer Center; Walker Cancer Research Institute; American Breast Cancer Foundation. These organizations received two stars: United Breast Cancer Foundation; The Avon Foundation; and the American Cancer Society.
