Survivor Series: Maryann Siniawski

Maryann Siniawski is a not one, not two, but a three-time cancer survivor. She was first diagnosed with breast cancer in 1996 at 41 years old. The cancer came back again in 2003 and after genetic testing showed she carries the BRCA2 mutation, cancer was detected for the third time in 2014. She thanks God that she has been cancer free for the last 29 years and now wants to do all that she can to raise awareness for those who may find themselves in a similar situation.
Almost 30 years ago, Siniawski went for a routine mammogram. Her doctor saw some microcalcifications, but was confident they were benign. However he wanted to perform a biopsy which, in fact, came back malignant. The early stage cancer was treated with a lumpectomy followed by radiation. Seven years later, she had a recurrence in the same breast. The cancer had infiltrated, so at that point she needed to have a mastectomy followed by chemotherapy, which was one of the hardest challenges she ever faced.
“The chemotherapy was pretty intense and I seriously thought the chemo was going to kill me. It was extremely tough for me. I missed my youngest son’s college graduation because I was so sick after my first treatment. That was heartbreaking for me,” Siniawski said.
She would not have been able to have made it through her treatments without the help of her family. Siniawski knows that it takes a community to get thru challenging times.
“My husband was working full time, but was there for me for whatever I needed when he wasn’t working. My Mom, who was still living at that time, was a big part of just being with me during the day: taking me to treatments, cleaning, cooking, doing laundry. She was with me as much as she could be,” she said. “When someone is down and out, you try to be there for them. I never really needed anything because if my Mom wasn’t there, my younger sister was. Of course I’m beyond grateful to my
family. They always knew what I needed without me having to ask. They were always there for me.”
Six years after Siniawski finished treatment, her younger sister, Sue Straatman, was diagnosed with ovarian cancer. Siniawski did everything she could to be there for her sister, as was their Mom.
“When going thru cancer treatment, stay strong which is easier said than done. Keep your faith, rely on your family and your friends for help, trust your medical team, and never think any questions you have are insignificant or not worth asking,” she said. “I think a big help is just put one foot in front of the other, take one day at a time. If you feel you can’t get through the day, break it down hour by hour. And if you can’t get through an hour, break it down minute by minute. Just try and stay strong,” she said.
Their father had previously died from prostate cancer when he was only 58 years old. After Siniawski and Straatman had battled cancer, the sisters went to a genetic counselor where they were informed that the three cancers were related. After having the genetic test, both sisters found out that they carried the BRCA2 genetic mutation, which explained their higher risk of contracting cancer. Siniawski’s son was later diagnosed with prostate cancer at the young age of 41. He, too, is BRCA2 positive. Siniawski said that cancer hit her family pretty hard.
While the decision to have the genetic testing is a very personal one, she thinks it is better to know if you have the mutation or not. Knowledge is power. Their older sister tested negative for the mutation. Siniawski’s younger son was tested and also has the BRCA2 mutation. Siniawski has 5 grandchildren who should be tested when they become eligible age wise to test (if they choose) because the mutation is present in their fathers. Siniawski’s oldest granddaughter was tested as soon as she turned 18 and, thankfully, does not carry the mutation.
“If you have the genetic mutation, there’s a 50% chance of passing that mutation down to your children. It doesn’t mean that they’re going to get cancer, it just means that they have to be more proactive with pre-screening and testing.” she said.
Siniawski said that while she feels blessed to currently be cancer free, it is also sometimes hard to be a survivor. Many survivors suffer with “survivors guilt”. To know that you are here and alive while you have friends or family who didn’t make it is devastating. However, when around other survivors, she cannot help but feel empowered.
“There’s nothing like being together with a group of cancer survivors. They call it a “sisterhood” and we call each other “warriors”. Every story is different, but yet you’re all connected because you are a survivor. We’ve all been through a lot, so just seeing other survivors with their community of fellow warriors makes my heart full.
Siniawski said that the most rewarding part for her now is going to events to help raise awareness and to support the cancer community. She explained that it is so important for women to both pass along knowledge and to be aware of their bodies.
From speaking at last year’s National Ovarian Cancer Coalition’s (NOCC) Annual Walk, to tying teal ribbons around trees for ovarian cancer awareness, to volunteering around Northwest Indiana and Illinois at various events, Siniawski does everything she can to support ovarian cancer education and awareness. There isn’t as much awareness of ovarian cancer as there is of breast cancer, so Siniawski is helping her younger sister with this mission. Her sister, Sue, co-founded a local group called Teal Hearts of Northwest Indiana, which Siniawski helps with.
Through everything she’s been through, Siniawski says she has her family and God to thank. “My religion, my Higher Power – it’s all about my faith. You know you’re putting your trust in the unknown and you just need emotional support from all sides. We’re very blessed because we’re a very close knit family. My love for my family is what got me through,” she said.
