Mastectomy and Beyond

Four months after my mastectomy in May 2016, it was time again for my well-woman exam. During the consultation with my doctor, she asked me what treatment plan I had decided on as a follow-up.

I told her I hadn't decided, that I was continuing with what I had been doing. She expressed respect for my healing choices but asked me to meet with an oncologist to ensure I had all bases covered. Since I was curious about what kind of post-op treatment plan an oncologist would prescribe, I agreed. So, a week later, I met with the oncologist she recommended. I left the appointment with a prescription for Tamoxifen and an $800.00 bill.
What was my trigger?
“I had a leaky gut. Since "all disease begins in the gut", it was the link I had been searching for.”
When I researched the side effects of Tamoxifen and how long I would be on it, I grew weary. The long list of possible side effects wasn't something I was willing to risk. So instead, I started down the research path again to find out if there was an alternative to Tamoxifen. Not only did I find the alternative information I was looking for, but I encountered a lightbulb moment.
The question I had asked, "what was my trigger?" was answered. I had a leaky gut. Since "all disease begins in the gut" (Hippocrates), it was the link I had been searching for. What is leaky gut? A condition in which the gut lining becomes abnormally permeable, meaning undigested food and toxins spill from your intestines into your bloodstream. I copied the following from Dr. Axe's website.
Signs of a Leaky Gut (1)

Gastric ulcers
Infectious diarrhea
Irritable Bowel Syndrome (IBS)
Inflammatory bowel diseases (Crohn’s, ulcerative colitis)
Small Intestine Bacterial Overgrowth (SIBO)
Celiac disease
Esophageal and colorectal cancer
Allergies
Respiratory infections
Acute inflammation conditions (sepsis, SIRS, multiple organ failure)
Chronic inflammatory conditions (such as arthritis)
Thyroid disorders
Obesity-related metabolic diseases (fatty liver, Type II diabetes, heart disease)
Autoimmune disease (lupus, multiple sclerosis, Type I diabetes, Hashimoto’s, and more) (2)
Parkinson’s disease (3)
Chronic fatigue syndrome (4)
The propensity towards weight gain or obesity (5)

“A leaky gut is a symptom of gut dysbiosis”
After my initial cancer diagnosis, the first thought that came to mind was my hypothyroidism diagnosis three years earlier. I wondered if there was a connection. When I began researching hypothyroidism, I learned hypothyroidism offsets hormonal issues created by digestive problems. (6) Everything pointed to a severe problem within my digestive tract. To learn what causes a leaky gut, click here.
The oddity is I didn't experience any glaring symptoms one would expect with a digestive issue, like cramping, bloating, or frequent bowel movements. However, I did suffer from constipation, which is hugely significant on its own. It's called IBS-C - Irritable Bowel Syndrome - Constipation. I also suffered bouts of depression that would come and go, but when I look back over my health history, the symptoms I was experiencing seemed subtle, and when issues arose, I dealt with them. Or so I thought. Click here if you would like to read how I arrived at a self-diagnosis of leaky gut.
The Poop Test
Since I self-diagnosed my leaky gut, I decided to get professional guidance and did a fecal test, and the results revealed I had gut dysbiosis. Gut dysbiosis is an imbalance in gut flora caused by too few beneficial bacteria and an overgrowth of harmful bacteria, yeast, and parasites. The more clinical term is "Small Intestinal Bacterial Overgrowth" (SIBO), and this term refers to the gut flora that crawled back into the small intestine from the colon, where it belongs. I learned that a leaky gut is a symptom of gut dysbiosis, and gut dysbiosis is linked to breast cancer! (7)
Gut dysbiosis expresses itself in a plethora of ways. I expressed it as a leaky gut that led to malabsorption that ultimately led to breast cancer. Someone else may express gut dysbiosis as IBS, ulcerative colitis, lupus, prostate cancer, fibromyalgia, rheumatoid arthritis or psoriasis/eczema, etc. (8). However, a gut dysbiosis diagnosis only confirmed my initial thought: breast cancer resulted because something was out of alignment. My cells mutated because of the toxic overload. Since discovering my microbiome was out of alignment, I set out to heal it. Click here to read what I did to restore my gut health.
