Growing up, many of us were raised in Christian homes practising specific morals and values, and anything outside of that was considered immoral or even ‘demonic’. However, what happens when you have a dual identity, and you embrace a bit of both?

On 29 June 2022, the University of the Free State Faculty of Theology presented a Table Talk Webinar with Dr Nomfundo Mlisa, titled ‘African Christianity: interconnections between religion, culture, and identity’. These webinars cover a variety of burning topics that deal with contentious issues across the country. Attendees emerged from various parts of the world, including Nigeria and Germany.

Dr Mlisa is a published author, qualified nurse, traditional healer, as well as preacher of the Word. Her talk was based on personal experiences of being Xhosa and being brought up as a member of the Methodist Church of Southern Africa in a strict Christian environment. She was on her journey to becoming a preacher when she realised that she needed to undergo the spiritual healing training (ukhuthwasa) and was faced with resistance from the church minister/s, forcing her to leave church because ukuthwasa was against the church policies.

Her journey has been challenging, because she only acknowledged her ancestral calling at the age of 42, following a series of occurrences that nearly cost her her children. Dr Mlisa hinted that, besides being against church policy, one of the reasons was that the Xhosa nation considered ukhuthwasa to be witchcraft due to the similarity in the pronunciation of words: ukhuthwasa, meaning undergoing spiritual training; ukuthwala, which is an ancient activity of gaining powers for wealth; and ukhuthakatha, meaning witchcraft.

“Rev Mabusela of the Methodist Church invited me back to the church and I was ordained as a reverend. However, my ordination was held at the East London Correctional Services, and it was then that I realised I was a prisoner of faith and tradition,” she said.

Is there a link between ukuthwasa and Christianity?

Besides the fact that philosophy could not prove the linkage, Dr Mlisa said that the link exists, but Christianity has strongly influenced Africans to integrate Christian values into their cultural value systems, as evidenced by various authors. This led to various people with spiritual calling disowning their cultural identities as well as their being.

“In Christianity, there are faith healers and prophets, whereas culturally, we have traditional healers; however, they have one objective, which is to heal the people. But because people wanted to accommodate their gifts in Christianity, such names were given. Furthermore, Christians recognise angels, while traditionally, ancestors are recognised,” she explained.

Looking into different practices in both the Traditional and Christian religions, they both have elements of training, ‘ukhuthwasa’. This is mainly because they all undergo different types of training under a senior person. A senior faith healer trains a junior, whereas a ‘gobela’ trains a traditional healer.

The society is also coming to accept all religions, with most people now wearing traditional healer beads everywhere, including work. There are also traditional healers who are modern doctors, demonstrating that these innate or hereditary abilities are a common language.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
