In Vedic astrology, the placement of Sun in the natal chart is considered to be one of the most important factors that influence a person's life. When Sun is placed in 2nd House for lagna Cancer, it can result in some interesting astrological predictions.

They are likely to prioritize accumulating wealth and assets in order to create a stable and secure foundation for themselves and their family. This placement also indicates that the individual is likely to have a good grip on their own resources and finances - they know how to manage money well.
Since the Sun is placed in its own house, it tends to take care of its own affairs quite well.
