How Navjot Kaur Sidhu got cured of Stage 4 cancer Navjot Sidhu said his wife triumphed over cancer due to her disciplined lifestyle and treatment mostly at govt hospitals. Navjot Kaur Sidhu is the wife of former cricketer and politician Navjot Singh Sidhu. She is a doctor by profession and a member of the Indian National Congress. She claimed to have beaten stage 4 cancer with ayurveda, which sparked controversy and legal notice. Navjot Kaur Sidhu is an Indian politician and former member of Punjab Legislative Assembly. She was elected from Amritsar East as a BJP candidate in 2012, but resigned in 2016 and joined the Congress party. Congress leader Navjot Singh Sidhu's wife Navjot Kaur has been served a Rs 850 crore legal notice over the "traditional" cancer recovery claims made by Sidhu. The notice was issued by the Chhattisgarh Civil Society (CCS), and sought an explanation from her over the tall claims made by Sidhu regarding her cancer recovery diet. Kaur has been asked to produce evidence to support Sidhu's arguments in seven days or else pay Rs 850 crore as compensation for the "misleading" claims.
