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.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
