Greetings Sisters & Supporters In honor of Valentine’s Day SOSI Presents… “The Lovin’ Ain’t Over”- An informative and entertaining session about intimacy and sexuality after cancer treatment  Bring your questions and concerns to this presentation and discussion of how cancer treatment affects sexuality, and how you can still have a good and satisfying sex life in spite of these effects.  Our presenter, Barbara Alterowitz, has been working on intimacy and sexuality after cancer treatment since the 1990s. With her late husband Ralph, who had prostate and stomach cancer and suffered the side effects of treatment, she wrote three books and many articles about sexuality and cancer, and conducted many support group and training sessions on the subject. She is a Sexuality Counselor certified by by AASECT (The American Association of Sexuality Educators, Counselors and Therapists), and with Ralph, the founder of the Center for Intimacy After Cancer Therapy (CIACT), a nonprofit that supports cancer patients and their partners. Barbara will bring 20 copies of her and Ralph’s highly rated book, “The Lovin’ Ain’t Over for Women with Cancer”, which will be for sale for $15. Here is an excerpt from the last chapter of the book:  “A couple who wants to have a physical relationship has many options, even if cancer treatment has caused changes that affect sexuality. Everyone can use some combination of the tools we have described in this book – working on a positive self-image as a basis for being a confident partner in the sexual interaction, using the power of touch, building on what turns each of the partners on, focusing on what makes the partner appealing, applying lubricants and moisturizers as necessary, communicating with the partner, and making sex all about sensuality and love and giving each other pleasure. These building blocks can help a couple get back on track toward a satisfying love life that is life-affirming and affirms the desirability and value of each partner.  “ Come dressed in red for LOVE! SOSI will provide Strawberries & Chocolate treats. Note: Due to the adult content, youth are not permitted at this support group meeting.

It's Time to Get Your Sexy Back!

Supporting Our Sisters International®

History & Mission

Supporting Our Sisters International (SOSI) founded by Madeline “MAD” Long-Gill, a survivorship organization was created to improve continuum care among African American and Hispanic breast cancer survivors. The goal of the organization is to help reduce breast cancer mortality for African Americans and Hispanics by focusing on health education for survivors.


Madeline established SOSI after many years of direct services as a training instructor for public assistance recipients, a homicide minister, domestic & sexual violence advocate, and a volunteer of 12 years with the St. Louis affiliate of Susan G. Komen Foundation. She served as President of Sisters Network Prince George’s County, an affiliate of Sisters Network Inc. These coupled experiences helped her understand the importance of health equity for all breast cancer survivors. Under her leadership, the awesome executive team of Sisters Network Prince George’s County reached over 10,000 people in less than 2 years through community health programs, workshops and medical screening participation. 


SOSI was created to support sisters worldwide with a message of health, hope, healing and quality care. Although the color pink represents breast cancer, SOSI has chosen to add a hint of green to denote living green aimed at helping women live healthier lifestyles to reduce their risk or recurrence of breast cancer.


SOSI has joined forces with survivors, family, friends, healthcare providers, researchers, community stakeholders, faith-based communities, and national organizations to create informative change within the breast cancer movement. SOSI believes we must support one another if we are to be the change. It will take all hands on deck to prevent and save lives!


Our mission: Through our exceptional attention to service, we are dedicated to saving lives by going beyond breast cancer awareness to empower, educate and inspire women around the world. We are committed to improving continuum care and services for the minority and under-served the community.

A celebration of iconic leaders and civil rights activists.

Black History Month, also commonly known as African-American History Month, is celebrated in many countries around the world including the United States, United Kingdom and Canada, to recognize the greatest leaders, events and important contributions of African Americans throughout history. 
Originally created in the 1920s as "Negro History Week" by historian Carter G. Woodson and the Association for the Study of Negro Life and History, and later — in the 1970s, starting at Kent State University — president Gerald Ford expanded the event to an entire month. Celebrated in February to coincide with the birthdays of Frederick Douglass and Abraham Lincoln, president Ford explained that the United States needed to "seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history.”
