Cancer Cells Grow Fast in a Lab: What You Need to Know

Ever wondered how fast cancer cells can grow? A PhD student from Nottingham, England, showed us in a viral TikTok video. Sophie Williams, 23, shared microscope footage of cancer cells doubling in just three days and forming colonies by the fourth day. But don't panic! This rapid growth isn't the same in our bodies. Cancer cells in a lab have plenty of food and oxygen, and they don't face competition or our immune system. In our bodies, cancer growth is slower and faces more challenges.Triple-negative breast cancer, a type shown in the video, is especially aggressive. It lacks certain receptors, making it harder to treat with hormonal therapies. Doctors like breast surgical oncologist Dr. Lauren Ramsey warn that this cancer can spread quickly if not caught early. Early detection is key, as it can help manage the spread and improve survival.
