Javernig realised something was wrong with her health earlier this year when she woke up in the night with a severe stabbing pain in her right breast.
Tests at the hospital revealed she had a faulty BRCA1 gene. Everyone has the BRCA1 gene, but according to the NHS, if there’s a fault or mutation in the gene the risk of an individual developing breast cancer is high.
Javernig was diagnosed with triple negative breast cancer - a rare strain of the disease that does not respond to hormonal therapy and affects just one in five breast cancer sufferers.
According to Macmillan Cancer Support, treatment for triple negative breast cancer can be particularly difficult, as women are usually given chemotherapy even when the cancer is low-grade.

Javernig has been a fan of Wonder Woman since she was given a costume of the superhero as a child.
On the last day of her chemo she donned the classic hot pants and red boots while other members of her family also dressed up as superheroes.
Her five-year-old twin daughters, Abby and Sophie, dressed as Iron Man and Cat Woman.
"Everybody was coming up and telling me how wonderful it was, they said I brightened their day, and that was half the point," she said.
Although the 43-year-old has now finished chemo she still has to undergo radiation treatment five days each week for a further five weeks.
She's also booked in to have a hysterectomy in the new year as a faulty BRCA1 gene also increases a person's risk of ovarian cancer.

Having a faulty BCR1 gene is genetic, but Javernig was unaware of a family history of it.
After her diagnosis a geneticist looked into her family history and found that four women on one side of her family had died of breast cancer in their forties.
Her mum and sisters are currently undergoing tests to check for the faulty gene.
Javernig is now encouraging other women to research their family history and find out if there is a history of the faulty gene in their family.
"A new painless, firm breast lump with irregular margins is a potential symptom of breast cancer," says Dr. Sandhya Pruthi, a breast cancer researcher at the Mayo Clinic. "The cancer diagnosis is confirmed following a biopsy of the lump." She notes that usually, women who are newly diagnosed with breast cancer are healthy and don't feel sick at all.

Other Symptoms(02 of10)

Another potential symptom/sign of breast cancer, Pruthi notes, is a new onset of persistent redness on the skin overtop the breast with an orange peel appearance. This would also need a biopsy to confirm a diagnosis of breast cancer. (credit:Image Source via Getty Images)
Metastatic Cancer Symptoms(03 of10)

"If the cancer is very advanced (metastatic) then the symptoms may also include weight loss, bone pain, headaches, nausea and persistent cough," Pruthi says. (credit:pamela burley via Getty Images)
What Are The Risk Factors?(04 of10)

Some commonly associated risk factors, Pruthi says, are menstruation before age 11, menstruation after age 54, a first pregnancy after age 35 and a family history of relatives diagnosed with breast or ovarian cancer. (credit:AP Photo/M. Spencer Green)
Are There Any Lifestyle Risk Factors?(05 of10)

"There is evidence in the literature that obesity after menopause, lack of regular exercise, consuming greater than more or more alcoholic beverages daily, and a high fat diet can all be associated with a higher breast cancer risk," Pruthi notes. But, she points out, "women need to know that any woman can get breast cancer even in the absence of any of these risk factors." (credit:Adrian Samson via Getty Images)
Can I Eat Anything To Prevent It?(06 of10)

There are no specific types of diets, Pruthi says, but rather women are encouraged to eat fruits, vegetables, fibre, and minimize their alcohol and fat intake, as well as get regular exercise. (credit:lola1960 via Getty Images)
How Do Doctors Determine Treatment?(07 of10)

"The most current treatment of breast cancer has taken on a individualized approach and is dependent on the biology or aggressive features of the breast cancer," Pruthi explains. "Breast cancer is a heterogeneous disease and this means that are many sub-types and different degrees of aggressiveness. So staging, which typically takes into account common prognostic features such as tumour size and if lymph nodes are involved, are no longer the only factors doctors use to determine treatment options."

So What Do They Look At?(08 of10)

"Today the biology of the tumour is also characterized by molecular markers (also known as predictive markers) such as if the estrogen or progesterone receptor is positive or negative and if the HER 2 protein is positive or negative," she says. "This helps decide who will benefit from a specific chemotherapy regimen, hormonal medications known as antiestrogens or who may need both chemotherapy and hormonal treatment."

What About Preventative Mastectomies?(09 of10)

"Preventive mastectomy is an option for women at very high risk for developing breast cancer because they are BRCA 1 or 2 gene positive or if someone has hereditary predisposition to getting breast cancer but chooses not to have the genetic testing done," Pruthi says. "It is prudent that women who are considering this surgery know their family history in detail. Based on the moderate or strong family history, your doctor would recommend you meet with a genetic counselor to go over the family pedigree and help decide who should test for the breast cancer gene, when to test and how to interpret the genetic test results before proceeding with this preventive surgery."

"High risk women who have had precancerous breast biopsies or strong family history may also be eligible to take preventive medications such as tamoxifen, raloxifene or exemestane to reduce breast cancer risk," Pruthi adds. (credit:art-4-art via Getty Images)
