Cervical Cancer Awareness Month is observed in September in South Africa to encourage women to go for screening to prevent it.

Cervical cancer is the second most common cancer among women in South Africa, and many die from it each year – but it can be prevented.

According to Dr Arina Meyer, medical practitioner in Kovsie Health at the University of the Free State, this is one of the reasons why it is important to be informed, take precautions, and raise awareness about the disease.

Cervical Cancer Awareness Month is observed in September in South Africa with the aim of encouraging women to go for screening to prevent it.

Although medical statistics paint a bleak picture, Meyer says there is hope. “It is important to know that cervical cancer can be prevented. And when it is diagnosed early, it can be treated.”

Statistics and causes

According to her, figures show the occurrence of cervical cancer to be between 22,8 and 27 per 100 000 women in South Africa. 

“More than 5 700 new cases are reported each year, as well as more than 3 000 deaths. Cervical cancer is the second most common cancer – after skin cancer – in South Africa.”

Meyer says when one look at these numbers, it is important to commemorate Cervical Cancer Awareness Month, as women need to be informed about their annual check-up, possible symptoms, and signs of the cancer.

Most cervical cancers are caused by the human papillomavirus (HPV), which is transmitted through sexual contact. Therefore, the HPV is seen as a sexually transmitted disease.

“There are different types of HPV. Some cause cervical cancer and other genital warts. One can develop one or both conditions, depending on the type of virus you have,” says Meyer.

Prevention and reducing the risk

According to her, preventative action is the best method. Going for a cervical screening every year when you become sexually active, such as a Pap smear or Pap test, will help in the early detection and removal of abnormal cells.

There is also a vaccine for protection against HPV, which is available from the age of nine. Meyer says there are two vaccines in South Africa.

“By getting the vaccine early, before any sexual activity, the spread of HPV – and therefore cervical cancer – can be prevented. Up to 90% of cancers can be prevented.
“Unfortunately, if someone has already been infected by the HPV, it cannot be treated by the vaccine.”

The UFS medical practitioner says the best ways to reduce the risk of cervical cancer are to go for an annual Pap smear, a follow-up after an abnormal test result, the vaccine, safe sex, and to stop smoking.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
