In October and November 2025 we released a twelve-part YouTube series explaining mesothelioma, and on January 8, 2026 we added a single overview video. Here they are in the order we suggest watching them, each with the guide page on our site that covers the same ground in more detail. They are general information from a law firm, not medical advice. Your own doctors are the people to ask about a diagnosis or a treatment plan.
Start here: the overview
Video · 28:30 Mesothelioma Symptoms, Causes, and Treatment Explained
Mesothelioma Symptoms, Causes, and Treatment Explained (January 8, 2026, about 28 minutes) covers what mesothelioma is, how asbestos exposure leads to it, its symptoms, how it is diagnosed and the main treatments. If you only watch one, watch this. Our guide, Mesothelioma: What It Is, How It's Diagnosed, and How It's Treated, is its written companion.
The series began on October 14, 2025 with Mesothelioma and Asbestos Cancer Explained, a 44-minute video that runs through every topic below in one sitting, with chapter markers. The short videos that followed break it into parts.
1. The basics
- How Cancer Starts: The Basics Explained (October 22, 2025). How normal cells grow, what makes a tumor cancerous, and how cancer spreads. Mesothelioma is a cancer of the mesothelium, the thin lining around the lungs, the abdominal organs, the heart and the testicles (guide).
- The History of Asbestos and Mesothelioma (October 31, 2025). Why asbestos went into so many products, and why the disease appears decades after exposure, commonly 20 to 50 years later. See our pages on asbestos and its history.
2. Types and cell types
- Types of Mesothelioma Explained (October 24, 2025). Mesothelioma is named for the lining where it starts. Pleural mesothelioma, in the lining around the lungs, is about 81 percent of U.S. cases; peritoneal, in the abdomen, is about 11 percent; pericardial and testicular forms are very rare. See pleural and peritoneal mesothelioma.
- Mesothelioma Cell Types Explained (October 30, 2025). A pathologist also classifies the tumor by the kind of cells in it: epithelioid (about 6 in 10 cases), sarcomatoid (about 1 in 10, the most aggressive) or biphasic (a mix). Cell type affects treatment choices and outlook. See mesothelioma cell types.
3. Symptoms
- Mesothelioma Symptoms to Know (October 27, 2025). Shortness of breath, chest pain, fluid buildup, tiredness and weight loss. These symptoms look like those of far more common illnesses, which is one reason mesothelioma is often found late. If you were exposed to asbestos and have symptoms that don't go away, see a doctor and tell them about the exposure.
4. Diagnosis
- How Imaging Helps Diagnose Mesothelioma (October 28, 2025). X-rays, CT, PET and MRI scans can show fluid, thickening of the lining or a mass, but scans alone can't confirm mesothelioma.
- How Biopsies Confirm Mesothelioma (October 29, 2025). For most patients, a tissue sample examined by a pathologist is what confirms the diagnosis and identifies the cell type.
Most mesotheliomas are found because a person sees a doctor about symptoms. No major medical organization recommends screening for mesothelioma, even for people known to have been exposed to asbestos.
5. Treatment
- Mesothelioma Treatment Options Explained (November 3, 2025). Treatment depends on where the cancer is, how far it has spread, the cell type and the patient's overall health, and is best planned by a team experienced with mesothelioma. See pleural mesothelioma treatment and peritoneal mesothelioma treatment.
- Surgery for Mesothelioma Explained (November 4, 2025). Surgery is not an option for every patient. For pleural mesothelioma it is reserved for carefully selected patients; for peritoneal mesothelioma, eligible patients may have surgery combined with heated chemotherapy delivered into the abdomen (CRS-HIPEC).
- Chemotherapy for Mesothelioma Explained (November 5, 2025). Pemetrexed with cisplatin, or carboplatin for patients who can't take cisplatin, has been a standard regimen for more than twenty years.
- New Mesothelioma Treatments Explained (November 6, 2025). Immunotherapy and clinical trials. The FDA approved the immunotherapy drugs nivolumab and ipilimumab together for pleural mesothelioma that can't be removed by surgery in 2020, and pembrolizumab with chemotherapy in 2024. Whether a newer treatment or a trial fits a patient is a question for specialists.
Our take
What this means if you have, or may have, an asbestos claim
These videos explain the medicine. For a claim, two other things matter most: the pathology report that confirms the diagnosis, and the history of where you or your loved one was exposed to asbestos, often decades ago. Keep copies of medical records and write down every job, ship, plant and product you can remember. Deadlines apply and vary by state. Our page for people who have just been diagnosed explains what to do first, and our mesothelioma guide covers the disease in depth.
