How Cancer Spreads and Survives
Why Understanding Cancer Spread Matters
For patients facing Stage 4 cancer, one of the most difficult parts of the diagnosis is understanding how cancer spreads—and what can be done to stop it.
Cancer spread, also called metastasis, happens when cancer moves from its original location to other parts of the body. In fact, the vast majority of cancer deaths are caused not by the original tumor, but by the effects of metastatic cancer.
While that can feel overwhelming, researchers are learning much more about how metastatic cancer cells survive, hide, and eventually grow in other parts of the body. These discoveries could point toward new Stage 4 cancer treatments and more personalized approaches to care.
New Discoveries About How Cancer Spreads
Researchers at Memorial Sloan Kettering Cancer Center (MSK), led by metastasis researcher Joan Massagué, PhD, are uncovering important insights into how cancer spreads.
One discovery is that metastatic cancer cells can become unusually flexible. They can access cellular programs normally associated with much earlier stages of development, giving them the ability to adapt to different environments and potentially resist treatment.
Researchers have also found that some cancer cells can enter a dormant state. Instead of actively growing, these cells can remain hidden from the immune system until conditions allow them to become active again. This may help explain why cancer can sometimes return long after initial treatment.
MSK scientists identified a signaling pathway called STING that may be important during this process. As dormant cells begin growing again, increased STING activity can make them more visible—and potentially more vulnerable—to the immune system. Researchers are studying whether this window could eventually be used to help immune defenses destroy metastatic cells.
Scientists are also learning that different cancers can use different strategies to spread to the same organ. Understanding those differences could eventually help doctors target the specific vulnerabilities of each cancer more precisely.
Can Genetics Predict Where Cancer Spreads?
Additional MSK research adds another important piece to the metastasis puzzle. Scientists analyzed genomic information from approximately 25,000 patients across 50 cancer types to investigate whether a tumor’s genetic mutations could predict whether—and where—it would spread.
Researchers found associations between certain genetic changes and patterns of metastasis, but genetics alone could not reliably predict exactly where an individual patient’s cancer would spread.
The findings suggest that metastasis is more complex than a single mutation. How genes are regulated, how cancer cells interact with their surrounding environment, and how tumors continue to change as they progress may all influence cancer’s ability to spread.
For patients, this research could eventually contribute to more personalized cancer treatment, monitoring, and assessment of metastatic risk as scientists combine genomic information with increasingly detailed clinical data.
What This Means for Patients
For people living with Stage 4 cancer, understanding metastasis is about much more than understanding why cancer spreads. It is about finding new vulnerabilities that researchers may eventually be able to target.
These discoveries could contribute to:
- New Stage 4 cancer treatment options
- Better strategies for preventing or controlling metastasis
- More personalized treatments based on tumor biology
- Improved use of immunotherapy and clinical trials
- Better ways to identify and target dormant cancer cells
Importantly, researchers emphasize that metastatic cancer is no longer universally viewed as an automatic death sentence. For some cancers, immunotherapy and other advances have made metastasis more treatable, while other advanced cancers are increasingly becoming diseases that can be controlled for longer periods.

What Cancer Cells Eat to Grow
What Cancer Cells Eat to Grow (Stage 4 Cancer Explained)
Why This Research Matters
For patients facing Stage 4 cancer, new treatments often begin with one important question: What is helping cancer grow—and how can it be stopped?
New research from Memorial Sloan Kettering Cancer Center is focusing on something many people don’t think about—how cancer cells use nutrients to survive.
By understanding how cancer cells “eat,” scientists are uncovering new ways to develop better cancer treatment options and improve outcomes for patients. This type of research may shape the next generation of therapies for people facing advanced cancer.
Understanding How Cancer Cells Grow
At the center of this research is Lydia Finley, whose work focuses on cancer cell metabolism—the way cancer cells convert nutrients into energy and the building blocks they need to grow.
All cells need fuel to function, but cancer cells often depend on certain nutrients more heavily than normal cells. This creates a potential opportunity for treatment.
If researchers can identify what cancer cells rely on, they may be able to:
- Block those nutrients
- Disrupt how cancer cells produce energy
- Slow or stop tumor growth
This research is already leading to important discoveries. In some studies, scientists found that certain molecules, called metabolites, can actually change how cancer cells behave—making them less aggressive and less likely to spread.
In another example, researchers studying a rare childhood cancer identified key nutrients the cancer depended on. They then used an existing drug, methotrexate, to target that process and slow tumor growth.
This type of research may not always lead to immediate treatments, but it plays a critical role in advancing clinical trials and new cancer therapies. Many breakthroughs start with understanding how cancer works at its most basic level.
It also helps explain why some treatments stop working over time. Cancer cells can adapt and find new ways to survive. By understanding metabolism, researchers may be able to stay ahead of that resistance and develop more durable treatment options.
What This Means for Patients
For patients with Stage 4 cancer, research like this represents something important: new possibilities for treatment.
Many of today’s most effective therapies—especially targeted therapy and immunotherapy—started with this kind of foundational research. What may seem like early science today can become tomorrow’s life-saving treatment.
Understanding how cancer cells survive could lead to:
- New Stage 4 cancer treatment options
- More personalized care based on how a patient’s cancer behaves
- Better outcomes with fewer side effects
But discoveries alone are not enough.
Patients must be able to access the right care, at the right time, and at the right place. Many of the most advanced treatments and clinical trials for cancer are available at leading cancer centers—but getting there can be one of the biggest challenges patients face.
Additional Insight: Why Metabolism Research Is Expanding
Research from Dana-Farber Cancer Institute reinforces the importance of this work. Scientists are finding that cancer cells do not all use nutrients in the same way, which means treatments may need to be tailored even more precisely for each patient.
Their research highlights how cancer cells can “reprogram” the way they use energy—allowing them to survive, grow, and even resist treatment. This supports findings from MSK that understanding how cancer cells use fuel is critical to developing more effective therapies.
By identifying these metabolic differences, researchers are working toward treatments that not only target the cancer itself but also cut off the pathways it depends on to survive. This may help explain why some patients respond better to certain therapies—and how new combinations of treatments could improve outcomes.
As this field continues to grow, it is opening the door to more personalized and effective cancer treatment strategies, especially for patients with advanced or treatment-resistant disease.
