In Vedic astrology, the placement of planets in different houses of a horoscope can reveal a lot about a person's personality and their life events. It is believed that the Sun, which represents power, authority, and ego in astrology, can significantly impact the 8th house for people with Cancer as their ascendant or lagna.
When the Sun is placed in the 8th house for Cancer ascendant individuals, it creates an enemy sign situation. The Sun represents the father figure and authority figures in general. Therefore this placement may indicate challenging relationships with these figures of authority throughout one's life.
The eighth house signifies death and transformation. When the Sun is placed here, it indicates that these themes will become prominent throughout one's life. For instance, it can foretell injuries or medical conditions that will be severe enough to cause some kind of transformation in the individual’s lifestyle.
Moreover, since Sun is also lord of houses [2], it takes care of these houses as well. This means that there will be an impact on finances and family relationships during this period for Cancer ascendants since both these areas are significant concerns for them.
Another important thing to note with this placement is that the Sun is a natural karaka of houses [1] and [10]. Hence any predictions regarding these two houses would also bear an effect during this period. Since the first house represents your overall health and well-being along with physical appearance which becomes more sensitive when influenced by Sun's energy chances are something might come up where one needs to pay attention to their physical health so as not to appear weak or less dominant during social interactions.
Meanwhile, since the tenth house rules over one's career path and professional standing in society if other factors favor then chances are there would be great growth opportunities coming their way.
Finally, let us also analyze how this placement impacts people's financial affairs due to aspects on second house[2]. The second house signified family, wealth and speech. With Sun Aspect in their second house, Cancer ascendant natives may have to spend more money than usual due to sudden medical expenses or other unexpected events. However, because the Sun is a natural benefic planet that brings fortune and good luck, this may also signify a sudden influx of wealth or financial gain.
In conclusion, when it comes to astrology for Cancer ascendant individuals with the Sun placed in their 8th house (in enemy sign state), there are significant implications for one's circumstances. The placement suggests an increased focus on matters related to transformation/death as well as potential challenges with authority figures. On top of these are the effects on financial affairs and personal well-being/physical appearance that can arise during this period. While all of these astrological predictions should be taken with a grain of salt as planets hardly act alone but always interact depending upon their surroundings in one's chart the energies of the placement could manifest into real-life situations if other factors favor.''
