Tumors are not one enemy<\/h2>\n\n\n\n
A tumor may look like a single lump on a scan, but its cells can differ in their genes<\/a>, behavior, and survival tactics. Think of it as a crowded neighborhood where every house is built a little differently, which means one drug may reach many cells while missing others.<\/p>\n\n\n\n This diversity is called tumor heterogeneity<\/a>. A 2017 National Cancer Institute analysis found that drug-sensitive cells can die while resistant groups survive<\/a>, expand, and eventually dominate the tumor, although the pattern can vary by cancer type and treatment.<\/p>\n\n\n\n \u201cThe next big question in cancer is cellular heterogeneity, which allows it to survive treatments,\u201d Bettencourt-Dias said. Some cells escape the drugs and continue evolving into something new. That is the escape route researchers want to close.<\/p>\n\n\n\n To catch those survivors, researchers need more than an average reading from a piece of tumor tissue. Bettencourt-Dias points to high-resolution spatial proteomics<\/a>, a way to map proteins inside individual cells and show where those cells sit next to one another.<\/p>\n\n\n\n Proteins do much of the daily work in a cell, from carrying signals to repairing damage. Mapping them in place could reveal small pockets with different defenses, much like spotting a few people taking a side street while the main crowd moves in another direction.<\/p>\n\n\n\n A 2025 spatial cancer profiling project described distinct tumor microregions with different genetic, metabolic, and immune features. The interview does not present this technology as a ready-made cure, and researchers still need to learn which patterns reliably predict treatment resistance.<\/p>\n\n\n\n Her own laboratory focuses on centrioles<\/a>, tiny structures that help organize the cell\u2019s internal framework and support accurate cell division. They also help form cilia, microscopic antenna-like or tail-like structures involved in sight, clearing particles from airways, cell communication, and sperm movement.<\/p>\n\n\n\n Centrioles are copied as cells divide, carrying their organization from the first fertilized cell through a body containing about 30 trillion cells<\/a>. Bettencourt-Dias says humans inherit the first centrioles from the father because they form part of the sperm\u2019s propulsion system.<\/p>\n\n\n\n The correct number matters. Abnormal centriole numbers are associated with cancer<\/a>, while defects involving centrioles and cilia are also connected to microcephaly, retinal degeneration, obesity, and problems with the body\u2019s internal symmetry.<\/p>\n\n\n\n At the Barcelona institute, the broader plan reaches beyond cancer. Bettencourt-Dias wants researchers to combine curiosity-driven biology with artificial intelligence<\/a> and powerful computing to study how environments shape living things and to explore the design of new proteins or cells<\/a>.<\/p>\n\n\n\n The center also co-manages the European Genome-phenome Archive<\/a>, which securely stores and shares identifiable genetic, phenotypic, and clinical research data. Large resources like this give scientists more material for detecting patterns that would be difficult to spot one sample at a time.<\/p>\n\n\n\n The idea is to use AI to sort enormous amounts of information and decide which questions to test first. But Bettencourt-Dias presents technology as a partner to strong basic science, not a shortcut around experiments or careful judgment.<\/p>\n\n\n\n For Bettencourt-Dias, science offers society something broader than medicines and machines. \u201cProbably the most important thing science brings to the world is critical thinking,\u201d she said, pointing to decisions about news, health information, medication, and vaccination.<\/p>\n\n\n\n She argues that the lesson did not fully stick after the COVID-19 pandemic. Scientists and journalists both need better ways to explain uncertainty, evidence, and changing conclusions, she said, adding that \u201cwe have an urgent duty to find new ways to communicate.\u201d<\/p>\n\n\n\nRead More: M\u00f3nica Bettencourt-Dias, the first woman to lead Barcelona’s genomics center, says the handful of tumor cells that escape treatment is why cancer keeps coming back<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n
