Saturn rules 10th and 11th house is in 4th house in Cancer
Saturn's placement in the 4th house of the Vedic horoscope can bring a variety of effects to the native depending on several factors, such as the sign, aspect, and conjunction.
As you've mentioned, the Saturn is in Cancer sign. Cancer is the natural sign of the fourth house, and it's ruled by Moon. Saturn, on the other hand, represents discipline, restriction, hard work, and longevity. The combination of these two energies can make the native very hardworking and disciplined in their approach towards their home, family, and personal life. The natives with this placement are likely to have a conservative approach towards their family, property, and real estate.
However, the 4th house represents emotional stability, mental peace, happiness, and harmony. Saturn's placement in this house can cause some emotional and psychological turbulence and imbalance, especially during the early years of life. The native may suffer from anxiety, stress, and depression, which can affect their mental and emotional well-being.
On the positive side, Saturn's placement in the 4th house can bestow practicality, maturity, and a strong work ethic, which can help the native build a solid foundation for their personal and professional life. It can also indicate that the native will have a stable and secure home life, with a focus on traditional values, and long-term planning.
Overall, Saturn's placement in the 4th house can bring some challenges and obstacles, but with hard work, discipline, and a practical mindset, the native can overcome them and achieve success and stability in their personal and professional life.
