Rahu.
Rahu -it perceives exactly and is sure of what to do in a given situation, in other words, is decisive and focused on the cause and has an unwavering, undaunting quality. Since Rahu does not own a sign, it's adaptable but can still manifest its intrinsic qualities irrespective of the association or placement, the best placement is the Kendra or Trikona. It operates on the mental plane as it represents the severed head, this severance may be severance from attachment if it manifests in a positive way, it should be seen and observed as an axis.
The problem is that Rahu is considered to the astrological dustbin, can cancerous growth be attributed to Rahu Alone absolute" No". Jupiter is more responsible for expanding it for it owns the arterial system and partly owns the lymphatic system. Rahu expresses itself in two ways sudden and harsh and in a more subtle gradual way simultaneously, its the self-sacrificing or self-destructive mode of Rahu that assimilates in the form of chaos and upheavals in the life of the most, Since this part is clearly visible one tends to ignore the subtle and gradual inner working of the Rahu. Lal Kitab refers to Rahu as the hidden molten activity of the Volcano, while Ketu is considered to be a dust storm visible and plain yet somewhat destructive. Rahu represents all invasive outside influences to the physical body, the bacteria, the viruses, and other pollutants while Saturn is a fungal, degenerative, and wasting experience in the body. In our body cells replace new cells its an ongoing process but the cancerous cells refuse to be replaced and start multiplying creating a cancerous growth, since the attributes are similar to the nature of Rahu most astrologers attribute Rahu with it, but in real terms, it is just a part of the combination not the absolute of it.
Wisdom and higher intelligence are traits attributed to Jupiter, But intellect and learning come from mercury, perception, and emotions from Moon, logic and factual information from Mars, Saturn provides practical knowledge and common sense, Rahu prenomination, and to an extent intuition also.
