Assistant Minister of Health, Dr Alfred Madigele says no intestinal cancers were identified from 2010 – 2014 in Kweneng West.
He said the national cancer registry captures all information by district and Omang numbers throughout the country and not by constituency or ward.
Dr Madigele was responding to a parliamentary question raised by the Member of Parliament for Takatokwane, Mr Ngaka Ngaka, in which he wanted to know the number of patients diagnosed with intestinal cancer from 2010 to 2014 in the Takatokwane constituency.
The minister said water testing conducted in Kweneng West by his ministry did not find lime in excess of the normal range in the water, adding that there has not been any proven linkage between lime contained in drinking water and intestinal cancer.
“Water with lime, which is usually defined as hard water, has no reported adverse health effects on the human body. On the contrary, the minerals contained in hard water are known to provide an important supplementary contribution to total calcium and magnesium intake to the human body,” he said.
Dr Madigele said ingested lime interacts with acidic gastric juice and gets broken down into its constituent ions, adding that these are absorbed or excreted depending on the body needs, a process controlled by the action of 1,25 – dihydroxy-vitamin D, the hormonally active form of vitamin D.
