Dave Coulier gives thumbs-up during chemo treatment amid ‘very aggressive’ cancer battle

a “very aggressive” form of cancer. The “Full House” star, 65, shared an update on his cancer treatment on Friday, posting a photo on his Instagram story giving a thumbs-up during a chemotherapy session. “Putting a positive spin and sending love to all of you who are battling and going through chemo,” Coulier wrote alongside the snap.“And remember to laugh ❤️,” he added.In the photo, Coulier had an IV line that appeared to be connected to a chemotherapy port in his upper chest, which can remain in place for weeks, months or even years.

It allows for blood draws and medication administration without requiring needle sticks each time he is required to do either of the above, according to The Cleveland Clinic.It was only two days ago that Coulier revealed he had been diagnosed with “a very aggressive form of cancer,” stage 3 non-Hodgkin lymphoma in October.

The comedian learned of his diagnosis after suffering a bad cold and noticing swelling in his groin area. Those symptoms led him to visit his doctor, who ran some tests.“Three days later, my doctors called me back and they said, ‘We wish we had better news for you, but you have non-Hodgkin’s lymphoma and it’s called B cell and it’s very aggressive,’” Coulier told People.“I went from, I got a little bit of a head cold to I have cancer, and it was pretty overwhelming,” he shared. “This has been a really fast roller coaster ride of a journey.”According to the Mayo Clinic, white blood cells in patients with non-Hodgkin lymphoma grow abnormally and cause tumors to grow throughout the body.

Coulier’s form of the cancer, B cell lymphoma, is rare.The actor spoke more about his cancer diagnosis on the “Today” show on Wednesday.
