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.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
