When one woman, Jennifer Cordts, paid a visit to the doctors to complain of a large rash on her breast, she was initially informed that it was nothing to worry about.
Jennifer, who lives in Texas, was booked in for a mammogram, but the scan came up clear, with doctors surmising that it was just a rash being caused by the fact that her bra was too small.
But when the symptom persisted, Jennifer, 45, took matters into her own hands and began to search Google to figure out what was going on. After searching, Jennifer stumbled upon every woman's worst nightmaire - one of the first possible diagnoses was inflammatory breast cancer.
Jennifer explains how she was left terrified, admitting, "All I could think about was what I googled, and what I googled said that everybody dies. Nobody survives."
"It was the first thing that popped up. And it was late at night. Everybody was asleep. And I was terrified. I just had a bad feeling."
It was only after booking in for a biopsy that the mother was then diagnosed with the disease. Speaking about how she felt after the diagnosis, she said, "It took my breath away."

Devastatingly, doctors then gave her just 3 - 5 years to live - and since then, Jennifer has made it her mission to ensure that no other woman goes through what she did.
So what are some of the other breast cancer symptoms we should all know - including the ones you may not be aware of already?
Of course, the most well known sign of breast cancer can be a new lump, or swelling in or around the breast. Another early sign of cancer, which can often be missed, is the change in size, shape or feel of a breast. Cancer Research UK advises getting to know your breasts and how their shape fluctuates throughout the month, in order to know what's normal for you.
But another symptom women can miss is having an intensely itchy breast - something which may be mistaken as simply dry skin.
Early signs of breast cancer can also include an inverted nipple - meaning the nipple pulling back into the breast, and according to the NHS, a change in the size or shape of one or both breasts, bloodstained discharge from either of your nipples, a lump or swelling in either of your armpits, dimpling on the skin of your breasts, a rash on or around your nipple.
If you have any of these, it's best to get to the doctors immediately. Surprisingly, breast pain is usually not actually a sign of cancer.
Other symptoms of inflammatory breast cancer, the disease Jennifer has been diagnosed with, can include the boob being swollen, red, firm or hard, and hot to the touch. Equally, if you notice thickening of the skin of the breast, pitted skin, like orange peel, or discharge from the nipple, particularly if it's blood stained, get to a doctor ASAP.
