Cancer is an umbrella term for over 200 different diseases, each with its own subtypes, genetic mutations, and behaviors. This diversity means that a treatment effective for one cancer type or patient may be ineffective for others. Moreover, as tumors grow, their cells accumulate different mutations, creating subclones with unique characteristics.
Cancer cells have mutations in their DNA that allow uncontrolled growth and division, dodge usual mechanisms of cell death, and can often spread throughout the body. This is, in part, why the disease is so difficult to treat, with a wide variety of mechanisms and types that poses unique challenges.
Close to 1.8 million cases of cancer are diagnosed each year in the US, with more than 600,000 deaths (about 0.2% of the total population). This visualization tool offers a searchable database of aggregate statistics on common cancers by gender, race, state, and other demographic information.
Alcohol consumption is linked to at least eight different types of cancer, including liver, breast, and throat. The risk comes from ethanol, which turns into DNA-damaging acetaldehyde. Experts recommend limiting intake or quitting altogether to reduce long-term health risks.
Hosted by the National Cancer Institute, this tool provides interactive charts that display the likelihood of dying from various causes—including cancer—based on factors like age, sex, race, and smoking status. By contextualizing cancer risk among other potential health threats, users can create custom charts.
Cancer cells divide much more frequently than most normal cells. Most chemotherapy drugs are designed to interfere with cell division, thereby targeting harmful cells while attempting to leave healthy cells alone.
Stage 0 is in situ, meaning abnormal cells haven’t spread, while Stage 1 is further progressed but remains localized to the origin. Stage 2 and 3 show increasing tumor size and spread to nearby lymph nodes or tissues. Stage 4 indicates metastasis, meaning cancer has spread to distant organs.
Due to its proximity to Gulf oil production, an 85-mile stretch of highway linking Baton Rogue, Louisiana, and New Orleans is home to 25% of the country's petrochemical manufacturing. It's also one of the most polluted regions of the US, with cancer rates at 50% above average.
Cancer is a complex disease with many different types, each with its own pathology. The best treatment may depend on characteristics specific to each person—even if two people share the same type of cancer. No single overview of treatments exists, but this resource from the National Cancer Institute lets you explore different options, side effects, an A-to-Z library of cancer drugs, and much more.
At the heart of cancerous cells is the development of mutations—an ongoing and continuous process that happens frequently. So why don’t we get cancer immediately? The body’s immune system has developed intricate methods to detect and destroy cancer cells, catching the vast majority before they get the chance to evolve into tumors.
Cervical cancer is the fourth most common cancer in women globally. Almost all cases (99%) are linked to infection with high-risk human papillomaviruses. However, cervical cancer is both treatable and preventable—and we may be able to prevent most cases through vaccination.
