Solunars by Aldebaran Sidereal Academy

Monday night (Feb 5) Buckingham Palace announced that during King Charles III's benign prostate reduction surgery, cancer was detected. They are not acting alarmed, are expressing confidence in his treatment, and make it sound not terribly threatening.

They're also not saying what kind of cancer it is. That's strange, since the least threatening kind they likely would have found is slow-growing prostate cancer. I have to assume, therefore, that it isn't prostate cancer. To be discovered during that surgery, it could be rectal (which likely wouldn't have sounded louder alarms), bladder (moderate threat but caught early?), or something caught in a blood test.

King Charles (whom I haven't expected since the '70s would serve a long reign) is at a transition point in his life and, within about a year, has some unusual hardship. The diagnosis came almost precisely at Saturn opposite natal Saturn - a hard transit but more one of showing a new life phase and time to make some changes and realignments in life. It also occurred almost the exact day of a progressed New Moon, another "phase change, start a new life cycle" aspect. By Solar Arc, Saturn has just entered a 1° orb of conjunct natal Sun, which will build over the next (not quite) one year and is the most threatening to his well-being.

Transiting Pluto is also starting to square his Moon, and this will appear on angles of many SLRs over the next year or two, I'm sure. It also suggests existential confrontation and a bit of a shock.

According to his chart, his greatest health vulnerabilities are likely reflected by his Aries Moon, suggesting kidneys and urethra, bladder, and rectum as vulnerable sites. It seems unlikely that Mars in Scorpio (throat) is implicated, given how the cancer was found.

His background hard aspects are limited to Jupiter opposite Uranus. He has a foreground Venus-Neptune conjunction square Pluto mundanely, which is less likely to be a health issue. Jupiter-Uranus is not particularly an aspect of much medical pathology (at least, not as related to the cancer) and mostly shows insightful treatment and benefit from new medical technology.

I think it's likely bladder cancer, or another form related to the Aries parts of the body.

Price William's main transit a he moment is Pluto conjunct soon to square his elevated natal Jupiter and then square his MC. Royal elevations have occurred under such aspects. FWIW (and it is a very long-running transit), progressed Jupiter is only 0°12' from his Midheaven. There are no Solar Arcs involving personal points other than d Venus conjunct r Moon (exact almost six month ago), but d Saturn is now within half a degree of opposite his Venus.
