While you can use these ideas without Research Access, there will be more detail if you are a subscriber.
Start with a timed chart for a cancer—on a 90* dial of course as it makes aspect contact recognition so much easier and it will include the important axis factors. On the chart, use Research Access to find points for the specific type of cancer. Is it breast, lung, liver, pancreatic or what? There may be several asteroids for it. Enter those points on the chart. You may want to check Virchow for a pathology and Handley as a general cancer or disease indication. Asteroids King, Lynch and Strattonia are also general cancer points.
Now enter the factors for the metal, Cobalt: Brandt #3503, Seaborg #4856, Simonsen #24068 and Wood #1660. Cobalt is found in Vitamin B12 but there are lots of other sources and it is now rated as a class 1 carcinogen. Cobalt is reduced by oxygen. Oxygen points include Priestley and Lavoisier. It is expected that cobalt factors will occur in the axis of cancer asteroids. And, if, for example, the chart you’re using is for Liver cancer, also enter points for liver disease and give Jupiter a good stare! N-acetyl cysteine can reduce the cobalt level and melatonin can ease its impact. There are asteroids for these in the Medical Research area.
Certainly other things such as diet, intestinal function, cytochromes, genetics and more can be relevant, but just seeing the cobalt role should be amazing.
Similarly, high iron levels also encourage tumor growth. To see this in your cancer charts, enter Weinberg #6036, Hall #3299, Burt #6078 and Connors #13700.
Finally, enter the current 12-18 prior months of Eclipses on the chart. Even in the previous or longer year, Eclipses are “snapping” at the cancer axes and can intensify symptoms or signal metastasis. ( There are asteroids for metastasis in the Medical Research area but Virchow and Handley can signal that process..)
As well as leaving you astonished at astrology (again,) this exercise may be useful and important for clients.
