Despite significant progress, cancer continues to be the second-leading cause of death in the U.S. More than 2 million new cases of cancer are likely to be diagnosed in the U.S. this year. More than 618,000 deaths are expected from cancer in 2025.
There's also a huge financial cost that's growing rapidly. In 2020, treating cancer in the U.S. cost roughly $200 billion. By 2030, the total is projected to increase to more than $245 billion.
But with every problem comes an opportunity -- in this case, a massive opportunity to put your dollars to work to help the large and small companies that are developing new ways of diagnosing and treating cancer. Here's what you need to know about some of the leading cancer-focused healthcare stocks that investors should consider.

Top cancer stocks
Cancer stocks include drugmakers that focus on developing cancer therapies and companies that develop products used in screening for cancer. Some of these stocks are highly volatile, such as early-stage biotech stocks. Others, though, are more established and less risky. Here are four top cancer stocks to consider that include both small and large companies:
1. Guardant Health
2. Illumina

NASDAQ: ILMN
Key Data Points

NYSE: PFE
Key Data Points
Pfizer (PFE +1.48%) currently markets four blockbuster oncology therapies -- breast cancer drug Ibrance, prostate cancer drug Xtandi, bladder cancer drug Padcev, and blood cancer drug Adcetris. The company also has eight other cancer drugs that generate annual sales of at least $100 million.
Cancer is also a top focus for Pfizer's pipeline. The drugmaker has more than 50 oncology programs in clinical testing. While several of these programs are targeting additional indications for drugs that have already been approved, Pfizer also has promising new candidates, including experimental breast cancer drug atirmociclib.
The pharma giant has also used its large cash stockpile for key acquisitions that bolster its oncology prospects. For example, Pfizer acquired Trillium Therapeutics in 2021 to obtain its blood cancer programs and acquired Seagen, a leader in developing antibody-drug conjugates targeting cancer, in 2023.
Pfizer's success doesn't hinge entirely on its oncology products and pipeline, though. For example, the company is a leader in the migraine therapy market, with Nurtec ODT delivering strong sales growth.
4. Summit Therapeutics

NASDAQ: SMMT
Key Data Points
Unlike Pfizer, Summit Therapeutics doesn't have any approved products on the market. As a clinical-stage biotech company, Summit could be riskier than more established drugmakers.
However, Summit claims one of the most promising candidates in development -- ivonescimab. In May 2024, ivonescimab achieved better progression-free survival in patients with non-small cell lung cancer than Merck's Keytruda in a late-stage study conducted in China. Keytruda was the world's highest-grossing drug in 2024, with sales of almost $29.5 billion.
In October 2024, Summit completed enrollment in a global phase 3 clinical study evaluating ivonescimab as a second-line treatment for NSCLC. The company is also conducting late-stage studies of the drug as a monotherapy and in combination with chemotherapy as a first-line treatment for NSCLC.
There's no guarantee that ivonescimab will be successful in late-stage studies and win regulatory approvals. If the drug can achieve its potential, though, Summit Therapeutics could be a much bigger company a few years from now.
