This is a transcript of Episode 5 of the BRCA Gene Mutation and Cancer Awareness podcast.
Welcome to the BRCA gene mutation and cancer awareness podcast. I am Christina Henry of Midlifestylist.com. I am a Registered Nurse with a BRCA2 gene mutation. My podcast will raise awareness of BRCA 1 and 2 gene mutations and their link to an increased cancer risk. BRCA gene mutations affect males and females equally, but there isn’t a lot of awareness in the community of the cancers that male carriers are at risk of. My podcast aims to change that. I will also discuss other topics of interest such as genetic counselling and testing, cancer screening and prophylactic surgery. If you would like to know more about BRCA 1 and 2 gene mutations, this podcast is for you. Thanks for joining me.
The Link Between BRCA Gene Mutations and Pancreatic Cancer
The third most common cancer associated with a BRCA1 or 2 gene mutation is pancreatic cancer. Pancreatic cancer is the fourth most common cause of cancer death in the US and Australia, and has the worst five year survival rate (<9%).
A family history of pancreatic cancer is found in 5-10% of pancreatic cancer patients. Of the known genetic mutations involved in familial pancreatic cancer, BRCA1 & 2 are the most common. BRCA2 mutation carriers have a 3.5 fold risk of developing pancreatic cancer. The risk associated with BRCA1 is unclear – some studies suggest a 2.2 fold risk, others say there is no increased risk.
Currently surgery is the only curative measure, but only 15-20% of patients are diagnosed with resectable disease. Even if the cancer is resected, 75% of patients will experience disease recurrence within 5 years. These statistics are a grim reality for people with BRCA gene mutations, and one that I find very concerning. Because my father died from pancreatic cancer, I am at high risk.
Risk factors associated with BRCA1 and 2 gene mutations:
As well as a mutation in the BRCA1 or 2 gene, certain risk factors can increase the likelihood that cancer will develop. For pancreatic cancer, an increased risk is associated with the following:
- cigarette smoking,
- chronic pancreatitis,
- diabetes (especially type 2 diabetes),
- liver cirrhosis,
- being male,
- exposure to certain chemicals used in metal refinery,
- stomach infection with Helicobacter Pylori (which causes stomach ulcers)
- and a high fat, meat based diet.
A decreased risk is associated with a low-fat, high fruit and vegetable diet and quitting smoking. The single environmental factor associated with pancreatic cancer is cigarette smoking, which is estimated for approximately 25-30% of all pancreatic tumours.
High risk patients are first degree relatives of someone with pancreatic cancer, have Reutz-Jeghers Syndrome, or have mutations in BRCA1 or 2, ATM, PALB2, or Lynch Syndrome genes, and have first or second degree relatives with pancreatic cancer.
We do have an opportunity to reduce our risk of many types of cancer, but not pancreatic cancer. Lifestyle choices can help but we can’t have risk reducing surgery. Watch for symptoms such as the following:
Symptoms of Pancreatic Cancer:
- Loss of Appetite
- Abdominal and mid-back pain
- Changes in bowel movements
- Unexplained weight loss
- New-onset diabetes. Symptoms of diabetes may include excessive thirst, a high or low blood sugar level, increased urination or blurred vision
- Jaundice – yellow skin or eyes
- Itchy skin
- Enlarged gall bladder
- Changes in taste
- Blood clots.
Like ovarian cancer, the symptoms are vague and may indicate a number of health issues. Early stage pancreatic cancer rarely causes symptoms which makes it difficult to diagnose. Seek medical attention early if you suspect that something is wrong. Be an advocate for your own health, be proactive with screening and maintain a healthy lifestyle.
Screening for Pancreatic Cancer
At present there is no clear consensus on the optimal screening method for pancreatic cancer, the age to initiate and stop screening, how often to screen and the ways to treat patients with a tumour. Screening may include MRCP (magnetic resonance cholangiopancreatography), or an endoscopic ultrasound. The American College of Gastroenterology recommends that high risk patients should be screened yearly. They recommend a EUS and/or MRI beginning at age 50 or 10 years prior to the earliest age of pancreatic cancer diagnosis within the family.
The Pancreatic Cancer Action Network (PanCAN) recommends that all pancreatic cancer patients receive genetic testing for inherited mutations as well as genetic counseling. For those with cancer, BRCA mutations can inform and improve treatment. Cancer cells with a BRCA mutation may respond particularly well to a certain type of chemotherapy as well as a targeted therapy called PARP inhibition. The PARP inhibitor Olaparib is recommended for patients with metastatic pancreatic cancer who have a BRCA1 or 2 gene mutation and whose tumour previously responded to a platinum based chemotherapy.
Pankind, the Pancreatic Cancer Foundation of Australia, is currently running a campaign because they aim to triple the survival rate of pancreatic cancer by 2030. Through funding research, particularly into screening for pancreatic cancer, Pankind hope to improve the current outcomes for patients and their families. Medical research is the single most important factor improving patient survival. I will add a link in my blog to Pankind’s website where you can donate if you wish.
The Australian Pancreatic Cancer Genome Initiative is conducting one of the research studies currently in Australia. The trial is using EUS (endoscopic ultrasounds) to screen people at high risk of pancreatic cancer. Hopefully the results of this research will improve detection and survival rates for people with pancreatic cancer. There is a link to this information on my website.
My Experiences With Pancreatic Cancer Screening
Unlike breast and ovarian cancer, I can’t have prophylactic surgery to reduce my risk of pancreatic cancer. My best bet is to have screening which will hopefully catch it at its earliest stages, when it is able to be resected. My gastroenterologist has recommended a MRCP, possibly alternating with EUS. Unfortunately when you have a BRCA2 gene mutation the fear of cancer is always there, but being proactive with screening will hopefully be enough to keep it at bay.
A couple of weeks ago I had an MRCP which is an MRI of the pancreas and surrounding areas. MRIs are horrible. I’ve had breast MRIs in the past which are extremely unpleasant as you need to lie still while lying face down with your breasts dangling through holes cut out of a board which applies pressure to your upper chest. Your arms are extended above your head in such a way that your shoulders cramp up but you aren’t allowed to shift position to relieve the pain, or even breathe deeply.
I thought the MRCP would be a bit easier than the breast MRI because I’d be lying on my back. But it wasn’t. My arms were still extended above my head for the entire torturous 30 minutes. The fear of stuffing the test up and having to redo it caused an anxiety attack and claustrophobia. My muscles in my neck, shoulders, arms and upper back went into spasm. Next time I’m requesting a sedative as every time I have one my reactions get worse.
Waiting For Test Results
Waiting for the results never gets any easier. The reality of having a BRCA2 gene mutation is that we need frequent screening, most of it painful, unpleasant and sometimes scary. Last week I had a gastroscopy and colonoscopy. The prep for that was brutal! Thankfully those tests came back clear as well.
When you’re cleared of cancer once again it’s almost a euphoric feeling. It’s hard to describe the constant underlying anxiety of having a gene mutation that increases your risk of cancer. At times I wonder if I’m a hypochondriac or overthinking this, but my doctors reassure me that my paranoia is justified. The main reason I decided to have prophylactic surgery to remove my breasts and ovaries, was to reduce my risk of cancer and to avoid these stressful and painful screening tests. My risk for ovarian and breast cancer is now less than the general population.
My Father’s Pancreatic Cancer
Watching my dad die of pancreatic cancer was soul destroying. He had been unwell for years, mostly due to prostate cancer. He needed an indwelling catheter to drain his bladder but it kept getting blocked with blood clots. This lead to frequent hospital admissions and very poor quality of life. He also had many urinary tract infections. During one of those hospital stays he had a CT Scan which showed his pancreatic cancer, quite by chance.
Dad’s health declined rapidly and he lost a lot of weight as the pancreatic cancer wrecked havoc with his appetite. His oral fluid intake was restricted because his sodium level was dangerously low. This meant he couldn’t enjoy two of his favourite things, food and alcohol.
During his final hospital stay he was hallucinating because of the low sodium. His hands were swollen and painful because he couldn’t take his gout medication. He was praying constantly that God would end his suffering. To see my strong dad in this way was heartbreaking. It took just seven months for pancreatic cancer to take him.
Dealing With The Emotional Side of Cancer Screening
My fear of getting pancreatic cancer is justified because it’s hard to diagnose in the early stages and has one of the highest mortality rates. Being aware of this means I will do the screening, no matter how much I hate it. During the long, sleepless night before the colonoscopy I cried for my dad. It’s so unfair that this genetic mutation has ripped my family apart.
My way of dealing with days when I feel upset or depressed, is by keeping focused on maintaining my health. I keep searching for information about BRCA gene mutations because there are currently many research studies being done worldwide. The knowledge I gain will help me to stay as healthy as possible and hopefully minimise my risk of cancer. Take a look at my resource page as I have included links to many of these sources.
My next episode will focus on prostate cancer and its link to BRCA gene mutations. As I have mentioned already, my father was a BRCA gene mutation carrier who had prostate cancer as well as pancreatic cancer. My grandfather passed away from prostate cancer and my brother was diagnosed with Stage 4 Prostate Cancer last year. During my nursing career I have worked in urology wards and have cared for many men with prostate cancer. I look forward to sharing this information in my next episode.

Hi Christina, I’m glad to hear your tests came back clear. Your proactive approach to take care of your health is excellent. Thank you for sharing this valuable information with #weekendcoffeeshare.
Hi Natalie, thank you – it was a big relief to get the all-clear. I lost mum at a young age so that’s why I am proactive with my health. Plus, seeing people in advanced stages of cancer in my nursing job also impacts my decisions. Thanks for your feedback. Regards Christina
Hi Christina. This topic always gets my attention for 2 reasons.
1) I was 8 or 9 when my mom brought me to her room because she wanted me to know that she was sick and showing me her breast, wanted me to touch this lump that might kill her. It was a tough message for this little kid. But she survived and another story began.
2) While working in Colorado Springs in the late 1990s, I had a team who stepped up to help a young woman who was in trouble. I thought her story might encourage you because we won a battle in the war against MBC. I’ve shared this link around a lot because I’m so proud of these people.
Hi Gary, thank you for sharing Jacquie’s story – it has some very important lessons there about being selfless and giving when someone needs help. You made such an impact in her life which was beautiful. That’s the kind of impact that someone never forgets – and she was able to repay you with a phone call when you needed it. You were obviously impacted by your mother’s breast cancer at a very impressionable age. It does change our outlook on life – you obviously became very compassionate because of it. Thank you so much for commenting, regards Christina
I agree. I would have told you that I already knew all this, but to see it acted out on behalf of someone we barely knew was powerful stuff.
Thanks for reading her story and for all you’re doing to push back on cancer.
I can hear the fear and see it too in some parts of your posts about what you now know. Is it better to know, I muse? I don’t have an answer for that either. My Dad had a really good friend who was diagnosed with pancreatic cancer and was dead within weeks. It’s an awful awful disease and I am so sorry your Dad suffered as he did.
Thank you for linking up for #LifeThisWeek last Monday. I am always pleased to see my old(er) and new(er) blogging friends link up. Your comments make my Mondays rock. Next week, the optional prompt is Self Care Stories. I hope to see you there too. Denyse.
I have often wondered that too Denyse. My brother has always put his head in the sand, but he is happily oblivious. Knowing all that I know about my high risk of cancer does my head in sometimes. I have heard of people having their kids genetically tested for BRCA at the age of 16! I think that is far too young personally. Even at my age it is hard to deal with the anxiety about the risk. That is why it’s so important that people have genetic counseling before they have these tests done.
I’m so glad my comments make your Mondays rock! Reading your posts is always a highlight of my Monday as well. Regards, Christina
Hi Chrsitina, so pleased about your results. Thanks for sharing all this valuable information.
Hi Debbie, thanks so much. It’s always a huge relief to get the all-clear. Take care, Christina
