The effect of harmful diet as well as activities of the mother causes congenital anomalies. The psychology of pregnant woman may also affect the foetus growth in her womb. Vedas considered the fact that for achievement of conception, happiness and good psychology of woman is an important factor [1]. The period of pregnancy and the intrauterine environment are crucial to the tendency to develop diseases like Cancer, hypertension, diabetes etc. Similarly, the maternal lifestyle, particularly diet, exercise and smoking during pregnancy, have an important role in determining the risk to develop diseases that manifest themselves both during childhood and particularly in adulthood [2]. Maternal behaviour during early periods of life can alter the epigenetic state of the foetal DNA. Maternal stress and maternal–placental–foetal biological mediators of stress can affect foetal development. In fact, it has been showed that exposure to maternal psychosocial stress during intrauterine life is associated with significantly shorter leukocyte telomere length in young adulthood, a predictor of disease onset and mortality. The present literary / conceptual study thus focuses mainly on interpreting these reviews, on the basis of modern scientific knowledge and intervention of personalised Dincharya & Ritucharya to prevent prevalence of cancer.
