It is possible in Astrology to diagnose a disease well before its actual appearance in the body. A disease can be expected,

When any planet receives bad aspects like square (90 deg) and opposition (180 deg).

When bad planets (Saturn, Mars, Rahu, Kethu, Uranus, Neptune, Pluto) are posited in bad houses like 6th house (place of disease), 8th house (place of longevity) and 12th house (place of death).

When bad planets occupy the signs: Virgo, Scorpio and Pisces.

When bad planets occupy the Ascendant (place of body, mind and soul).

Death can be predicted when Sun, Moon and Ascendant - all the three are afflicted.

I will use it just for reducing the pain and healing when disgnosis is not getting find or the pateint is not getting better
