Can cancer be hidden?

Some cancers can be present for months or years before they’re detected. Some commonly undetected cancers are slow-growing conditions, which gives doctors a better chance at successful treatment.

Can cancer cells hide from chemotherapy?

In their 3-D cell culture system, treatment with these antibodies in combination with chemotherapy killed most tumor cells—including dormant cells—hiding in the perivascular niche.

Is a cancer lump visible?

Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.

Do blood tests show cancer?

With the exception of blood cancers, blood tests generally can’t absolutely tell whether you have cancer or some other noncancerous condition, but they can give your doctor clues about what’s going on inside your body.

Can cancer go undetected for years?

A study conducted by researchers at Stanford University School of Medicine provides strong new evidence that malignant tumors may grow undetected in the body for a decade or more before they can be sniffed out by the most sophisticated blood tests currently available.

When does cancer go dormant?

Dormancy is a stage in cancer progression where the cells cease dividing but survive in a quiescent state while waiting for appropriate environmental conditions to begin proliferation again. Quiescence is the state where cells are not dividing but at arrest in the cell cycle in G0-G1.

Are cancer tumors alive?

Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don’t die when they’re supposed to.

Can cancer cells eat other cells?

Researchers have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells. The study suggests that this act of cannibalism provides these cancer cells with the energy they need to stay alive and initiate tumor relapse after the course of treatment is completed.
