January 25, 2019 — French startup company Wefight unveiled the English version of its Vik Breast chatbot for breast cancer patients at the 2019 Consumer Electronics Show (CES), Jan. 8-11 in Las Vegas. Vik Breast is a virtual companion that uses artificial intelligence (AI) to respond to almost any patient question 24 hours a day, 7 days a week.
Doctors are not available 24/7 to answer all the concerns a patient may have during treatment, which can make patients anxious and frustrated. All the functionalities of the Vik application, launched in 2017 in France, are adapted to breast cancer, in order to respond as precisely as possible to any questions the patients may have.
Vik Breast is freely available online for iOS and Android platforms, and via Facebook Messenger. The chatbot uses AI that allows it to respond efficiently at any time.
Vik Breast provides advice on:
- Treatment: how medication be taken, how to deal with the side effects;
- Life Quality: nutrition, sport, social life;
- Sexuality: the impact of medication, psychology;
- Administrative information: refund, transport; and
- General Content: for detection, prevention methods, diagnosis techniques, chemotherapies or radiotherapies.
Furthermore, Vik helps the patient through appointments reminders, pill reminders, a side effects notebook, clinical trials recruitments, and the “question of the day” to share their experience and learn from others.
All the answers provided by Vik are written and checked by doctors or pharmacists. Moreover, all information is regularly updated in order to conform to national regulations and scientific publications.
