As well as posting a selfie while waiting for this removal surgery, Mark took to his Instagram stories to share some photos of the process, with the port pictured both in and out of his arm.
Detailing his journey as a whole, the 49-year-old revealed in August that he'd messaged his doctor in April regarding a lump.
"Hi Jill," read the text. "For the past couple days I’ve had this dull sore lump in my shoulder kind of right where it connects to my neck that could either be fatal lymphoma or a sore muscle. At what point should I be concerned and have it looked at?"
The doctor said Mark should be seen immediately, with him then publicly announcing his cancer diagnosis in June. He finished treatment in early September, and then announced that he was cancer free on September 29.
