symptoms I had before diagnosis - peritoneal not lung but figured I'd share what to watch for

Patient · · 86 views
So I was diagnosed in November with peritoneal mesothelioma stage II. I know a lot of people come here looking for lung cancer symptoms but I wanted to post about what I actually experienced because it might help someone recognize this earlier than I did.

I kept a symptom journal starting in like August so I could track what was going on. Main things I noticed:

Abdominal pain and bloating. This was the big one for me. Started as this weird fullness after eating even small meals. Then it progressed to actual pain, not sharp but this dull ache that got worse as the day went on. By October I couldn't fit into my regular pants.

Fluid buildup, my abdomen started swelling noticeably. I gained about 15 pounds in weight but it was all in my stomach area, which seemed odd.

Nausea and loss of appetite, couldn't eat much without feeling sick. Lost about 20 pounds overall between the fluid weight and not eating.

Fatigue, this was relentless. I'd wake up tired and just couldn't get through a full day without needing to rest.

Constipation alternating with other digestive issues.

I know the searches mention lung mesothelioma but peritoneal is actually more common than a lot of people realize, especially for people who worked with asbestos like I did at Johns-Manville back in the 70s and 80s. The latency period is crazy long, mine showed up 40+ years after exposure.

If you're experiencing persistent abdominal symptoms that don't improve with standard treatments, push your doctor for imaging. CT scan is what caught mine. Don't let them dismiss it as normal aging or IBS or whatever.

Yeah man, glad you posted this because most of what I read online is all about the lungs too. I got the pleural kind but what you're describing sounds rough. That whole thing about the weight shift is interesting because my doc mentioned something similar happens with fluid buildup, just in different spots depending on which type you get.

The fatigue part really hits home. After my EPP surgery back in February I felt like I'd been through a full rebuild, not just a tune-up like I thought. Took longer to bounce back than they said it would. But pushing your doc for imaging is spot on. We didn't mess around once we had questions, got that CT pretty quick and it made all the difference catching mine early.

Sounds like you caught yours earlier than a lot of folks do. That symptom journal thing is smart, wish I'd done that instead of just telling my doctor "yeah I feel kinda off." Hope the treatment plan is working out for you.

Joe had some of those same digestive issues before his diagnosis and we kept thinking it was just getting older, you know? Really wish we'd pushed harder on imaging sooner like you did.

Thank you for posting this. Peritoneal really does get overlooked in these forums and the symptom picture you described is so consistent with what we see clinically, especially that pattern of early satiety (the fullness after small meals) progressing to visible ascites (fluid accumulation in the abdomen) over weeks.

The 40 year latency you mentioned is real. The literature on Johns-Manville workers specifically, including the Selikoff cohort studies from Mount Sinai, documented latency periods averaging 35 to 45 years for peritoneal presentations. So people who had occupational exposure in the 60s, 70s, 80s are still in that window right now.

One thing worth knowing: peritoneal mesothelioma actually has some of the more encouraging treatment data in this disease overall. The Sugarbaker HIPEC (heated intraperitoneal chemotherapy, basically a surgery combined with heated chemo directly in the abdominal cavity) protocol showed meaningful survival benefit in selected stage II patients in multiple studies including data published through the Washington Cancer Institute. Not everyone is a candidate but it's worth asking about specifically.

Your point about pushing for imaging is exactly right. I've seen patients who spent 8 or 9 months cycling through GI referrals before anyone ordered a CT. By the time someone looks, staging matters enormously.

Please make sure you're talking to your oncologist about all treatment options, including whether you're being evaluated at a center with specific peritoneal mesothelioma experience. Not every cancer center sees enough volume to have strong expertise here.

Sorry if this was asked before but I'm really worried about my stomach now too. I had the chest xray for my lungs but nobody really talked to me about what else to watch for and now I'm reading this and getting kinda nervous.

Did you have any stomach pain before they found the fluid or did that come first? I'm asking because I've had this weird bloated feeling after eating for like a month or so and I didn't think it was related. My doctor said it was probably just getting older, I'm 68, and I figured he was right but now I don't know.

The thing about the long latency period really gets to me. I worked on wiring in some nasty old buildings back in the 70s and 80s too, and it's just sitting there in my chest waiting I guess. Thanks for posting this because people really do need to know about the belly symptoms too.

Thank you for posting this. Seriously. Peritoneal gets so much less attention and people spend months, sometimes over a year, being treated for IBS or ovarian cysts or just "stress" before anyone thinks to look further.

The symptom journal you mentioned is something I talk about in our Thursday group at the cancer center almost every week. People often discount their own experience because a doctor shrugged it off once, and having it written down, with dates, changes that dynamic completely. One woman in our group had documented six months of symptoms before her diagnosis and that record actually shaped how her oncology team approached her case.

The 40+ year latency piece is so important and I don't think most people grasp it. Research puts the average latency for peritoneal meso at somewhere between 20 and 50 years after exposure, so someone who worked at a plant in 1978 isn't thinking about asbestos when their stomach starts acting up in 2024. The connection just doesn't come naturally.

And you're right that peritoneal accounts for roughly 20 to 30 percent of all mesothelioma diagnoses, which is not a small number.

For anyone reading this who's feeling scared or overwhelmed after seeing these symptoms in themselves or a loved one, that fear makes complete sense. If it's sitting heavy on you, talking with an oncology social worker or counselor who specializes in this can really help process what's coming up. Your care team can usually refer you.

Thank you for taking the time to do this for strangers.

That's really good to hear that the journal approach is helping people in your group. I was honestly skeptical about whether keeping one would matter but having those dates and the progression written down made such a difference when I finally saw the oncologist. My primary care doctor had kind of brushed off the bloating as dietary, so when I showed up with actual documentation of the timeline it seemed to shift how seriously he took the imaging referral. Do you find that people are more likely to advocate for themselves with doctors when they have that written record? I'm curious if there's research on that because it definitely changed my experience.

My father-in-law was just diagnosed in September, so we're still pretty early in this. He has pleural but reading your post hit different because his initial symptoms got written off as just getting older too. Doctors kept telling him it was probably just acid reflux or his back acting up.

What really stands out to me from what you're saying is how long it took before anyone took it seriously. He was complaining about chest tightness and shortness of breath for like six months before someone actually ordered imaging. By then the fluid buildup was already significant. We're kicking ourselves now because he mentioned these things to his regular doctor multiple times and nothing happened until his wife basically forced him to go to the ER in a panic.

The symptom journal thing is smart. We didn't think to keep track of when things started or how they progressed, so now it's hard to piece together the timeline. The latency period you mentioned is what terrifies me honestly. He worked in construction in the late 70s and early 80s, so we're looking at almost the exact same window as you.

Can I ask about the CT scan? Was it flagged immediately or did your doctor have to look at it more carefully? We're trying to understand what questions to ask at his next appointment because we don't want to miss anything. Also wondering if the peritoneal diagnosis changed your treatment plan compared to what they'd recommend for someone with lung mesothelioma.

Thanks for sharing this. It's actually helpful to read from someone further along in the process.

Yeah the dismissal piece is so frustrating. Six months of those symptoms and nobody connected the dots? That's what happened to me too, except my primary care doctor kept saying it was probably IBS or something dietary. I actually have my symptom journal notes from August where I wrote "weird bloating, probably need to cut back on bread" because I was trying to self-diagnose instead of pushing harder.

With pleural the chest symptoms are different from what I had but the pattern is identical - doctors assume it's something common and benign. Has your father-in-law had a CT with contrast yet? That's really what made the difference for me. Also curious what his exposure history was, since the Johns-Manville connection is pretty specific to my situation but there are so many industries where people got exposed without even realizing it.
Family
yeah my brother had some of those same things before they figured it out. he kept saying his stomach was killing him and we all just thought it was his diet or something, you know how it is. he'd complain about not fitting into his clothes and we joked about him getting older but looking back there was definitely something going on that wasnt normal.

the thing that got us moving was when he couldnt even drive long hauls anymore without needing to stop and lay down. thats when we knew something was really wrong because my brother loves his truck, he wouldnt complain about that stuff unless it was bad. took him to his regular doctor in like June and they kinda brushed it off at first but we pushed for the ct scan and thats when they saw the fluid buildup. stage II when they caught it.

so yeah what your saying about pushing for imaging makes total sense. doctors dont always connect the dots especially if they dont know about the asbestos exposure. my brother worked construction back in the day and never really thought about it again until the diagnosis. your post might actually help someone recognize this earlier than my brother did because honestly we lost almost a year just thinking it was stomach issues.
Patient
That's actually really important, the fact that he couldn't work anymore. A lot of people miss how much this impacts daily functioning before they even get a diagnosis. Did his doctor eventually do imaging or did you guys have to push for it? I found that a lot of GPs just wanted to treat symptoms without really investigating what was causing them, and I'm curious if that was your brother's experience too.

The abdominal presentation is so tricky because GI docs will reflexively think IBS or acid reflux first, and it takes forever to get to imaging. My dad had the pleural form but we spent months with his primary care just treating him for GERD before anyone ordered a chest CT in March. By then he was already Stage IV. Your symptom journal is actually brilliant because it gives you that timeline, which is exactly what oncologists need to see the pattern.

One thing I've noticed managing his palliative care is that the fatigue piece gets underestimated. It's not just tired, it's this bone-deep exhaustion that doesn't respond to sleep because it's the disease itself driving it. The nausea and appetite loss compounds everything because then they can't get adequate nutrition to fight back. We've had to get really intentional about small frequent meals, sometimes just protein shakes because actual food feels impossible. His oncologist suggested we try ginger supplements and smaller portion sizes spread throughout the day instead of three meals, and that's helped more than I expected.

The weight redistribution thing you're describing, that localized swelling rather than general weight gain, is such a specific finding. It's genuinely one of those red flags that should trigger imaging immediately but so many clinicians miss it because they're not thinking peritoneal. Did they do a paracentesis to confirm, or did imaging plus clinical presentation get you straight to biopsy? That matters because some docs still want tissue confirmation and others will proceed with treatment based on imaging alone.

You're right that peritoneal gets overlooked in the general awareness. Occupational exposure history should be the thing that makes someone think about it but that requires actually asking about work history, which...yeah. Glad you're pushing this message out there.
Family
My dad's presentation was so different from yours but reading this really hits home. He had the lung involvement so it was more about the chest pain and this persistent dry cough that wouldn't quit, but the abdominal symptoms you're describing... that's actually something we didn't realize until much later. When they did his initial staging scans in March they found some peritoneal involvement too, which the oncologist said wasn't uncommon even with the pleural diagnosis.

The fluid buildup piece resonates because we dealt with that heavily. He had two thoracentesis procedures before we pivoted to palliative in October, draining what felt like gallons of fluid. The relief was temporary but real. I wonder if your team is doing any fluid management or if they're monitoring the ascites progression with follow-up imaging.

Your point about the latency period is so important. People don't realize how long asbestos sits in your body before anything shows up. My dad was a construction supervisor in the 70s and 80s too, different industry but same exposure window. Forty plus years feels insane until you actually see it happen to someone you love and then it makes terrible sense.

The symptom journal thing you did is smart. We started keeping detailed notes once he was diagnosed but I wish we'd had that baseline from months before. It would've helped us recognize the pattern earlier instead of assuming it was just getting older. Push for that imaging if you haven't already and if they're not doing regular follow-ups demand it. Peritoneal can progress differently than lung involvement and honestly the imaging is what actually tells the story.

How are you managing the pain and nausea now? That was one of the hardest parts for my dad to deal with even on good palliative protocols.
