Despite the fact that his cancer battle is an ongoing one, witnessing King Charles perform his royal duties speaks volumes of his improved health, or at least the public hopes this to be true.

For the head of the British monarchy to speak openly of their health issues isn’t something the public is used to. That is one of the reasons why Charles’ openness about his cancer stunned many.

However, no further details have been revealed, such as the type or stage of the cancer. What’s more, it doesn’t seem like the Palace will share any additional information in the near future.

What we know is that most cancer treatments take a lot of time.

“It’s very common for treatment to be ongoing for very long periods of time, as is the treatment that the Princess of Wales went through, which is an intense period of treatment over a year, and then it comes to a point where it’s on an end, and she’s on that recovery from some of the impacts of her treatment,” Lee told Sky News.

So we’ve got immunotherapy, chemotherapy, surgery, hormone therapy. There are all sorts of different treatment modalities. And so it’s not surprising at all.”
