Moshe Kasher's Tonsil Cancer Diagnosis

American actor and comedian Moshe Kasher recently revealed that he had recently undergone surgery after being diagnosed with tonsil cancer, a type of oropharyngeal cancer. The 46-year-old actor, who made a guest appearance in the hit medical drama The Pitt, shared that the diagnosis was his “worst nightmare” as his father had died from throat cancer.

On June 21, 2026, Kasher revealed his diagnosis to the public through an instagram post. The actor shared that he had found "a bump on my tonsil" while filming The Comeback King and a subsequent check-up led to a diagnosis of early stage tonsil cancer. He also added that his cancer was found to be caused by human papillomavirus (HPV), a virus typically spread through sexual contact.

“It was cancer, which did not rule so hard,” Kasher wrote.

In an episode that Kasher and his wife, Natasha Leggero, recorded for The Endless Honeymoon podcast, Kasher detailed his entire cancer journey thus far, from discovering the tumor in his tonsil to the biopsy that confirmed his cancer diagnosis. Despite his diagnosis, Kasher remained as positive as he could.

"I'm going to be ok. The road to ok is going to be long and pretty arduous," he shared.

Following his cancer diagnosis, Kasher underwent surgery, which he dubbed “the most terrifying and consciousness consuming experience of my life”. He shared that the surgery removed his tonsils and 25 lymph nodes from his neck.

"I'm in pain and I'm in the middle of a very difficult process. It's gonna be a long summer. But the good news is the cancer I have has an incredibly high cure rate (in the 95% zone). I will find out next week if I need radiation or not but regardless I will be okay and back to being a cool dude ASAP," he shared.

Kasher shared that his experience with cancer made him really grateful for his life.

“Thanks to Natasha and all of my wonderful friends who have been so supportive. I woke up on that operating table so flooded with emotions and gratitude for my life and the gift of consciousness. I can’t wait to go back to work. but for now — I breathe. I walk. I eat. I survive. I live,” he wrote.

By sharing his story, Kasher also hopes to encourage his followers and the public to get screened for cancer. “HPV positive tonsil cancer is an epidemic in men under 55. Get checked and vaccinate your damn kids,” he shared.

According to the US Centers for Disease Control and Prevention, HPV is the most common sexually transmitted infection in the US. Additionally, HPV is thought to cause 60–70% of all oropharyngeal cancers in the US. It is also associated with other types of cancer, such as cervical cancer.

However, there are vaccinations available, which can offer protection against the types of HPV most commonly associated with cancer.
