Cancer: The dreaded term for malignant growths and lumps. Saturn, Moon and dusthanas 6^th, 8^th and 12^th seems to figure prominently in the charts of cancer patients. It relates the Lagna or its lord to the 6^th, 8^th & 12^th house or their lords. These dusthans rule such traumic situations or events as would change the entire course of one’s life. Ketu also plays an important role as it is difficult to detect and diagnose Cancer.

Saturn characteristics of all that hardens, hinders, depletes, and suppresses would seem to be the best fitted planet to be associated with cancer. Moon, ruling the mind, and also all the excretions in the body system would also fit well in this context.  All lumps and tumors are the accumulations of secretions that have been clogged or otherwise prevented from normal movement.

A study of several charts of cancer patients has shown a link between Moon and Saturn.  This link is found in the Navmasa Chart.  This does not mean necessarily mean that all charts where the Moon and Satrum are correlated are cases of cancer.  But the majority of cancer cases have the moon-saturn disposition.

If Moon is afflicted in Navamsha  chart by Saturn through positioning, aspecting or conjunction, it indicates the disease of cancer. Dashas or directional influences must also be seen for the disease of cancer.

8th House in Medical Astrology:

The 8^th House rules diseases and death. This is the most important malefic house in a horoscope. The 8^th lord is the most malefic planet and can destroy any Bhava or House. The 8^th lord in the 8^th is considered to be good for longevity. All sorts of misfortunes are given by the lord of the 8^th.
The 8^th House indicates disease, defeat, punishments, accidents, longevity, mode of death & surgery. Saturn, the Ayus karaka or significator of longevity is considered good in the 8^th.

To understand whether a disease will be chronic, study the 8^th house in detail. Malefic planets spoil the 8^th house significations.
Whenever the lord of the 8^th house is afflicted by malefic planets, the native undergoes operation connected with reproductive organs and sex.
The malefic houses in Astrology are known as Trika houses, viz. 6^th, 8^th & 12^th.If there are no benefic aspects to the rulers of the 6^th, 8^th and/or 12^th houses, then we should find persons whose planets create harmonious aspects. If that person is the doctor or a healer, healing will be successful.

Malefic planets like Sun, Mars, Saturn as lords of Kendras(1, 4, 7, 10)are benefic. Benefic planets namely Moon, Mercury, Jupiter and Venus as lords of Kendras are malefic, but posited in Kendra are benefic. Benefics hemmed between malefics loose their benefic effects. Benefic aspect of Jupiter reduces malefic results. Aspect of Mars and Saturn give malefic results. Moon and Mercury in association with malefics become malefic.The malefic results will be experienced during the major period, sub period and sub sub periods of malefic planets. Planets posited in 6-8 position cause harm during their Dasha or Antar Dasha periods.
