Pluto In Cancer. The First World War began not long after Pluto settled down to its slow crawl through Cancer (1912–3 to 1937–8), emphasizing fruitless effort and death on an appalling scale. As with Neptune (in that sign at roughly the same time), here the disruption of home and family life was almost worldwide, and those born during this period suffered again during the Second World War. When Cancer is a person’s Sun, Moon, or Ascendant sign, the powerful emotions of that sign are further heightened by Pluto’s compulsive and intense presence. These individuals have particularly powerful and determined responses, which will either make them pull right back or cause them to explode emotionally. This influence is increased when supported by other planets in water signs.
