BIOL 304 is UMGC's three-credit overview of the biological basis of cancer, designed for both science and non-science majors.
The University of Maryland Global Campus states the goal as applying knowledge of cancer biology to adopt appropriate lifestyle strategies and evaluate current treatments. The course examines how cancer develops and progresses at the cellular level, including the roles of genes and proteins.
Cancer is a topic surrounded by misinformation and strong emotion. The course asks you to replace headlines with mechanisms: what has gone wrong in the cell, and how a treatment or a lifestyle change acts on that problem.

Key Concepts Explained
Oncogenes and Tumor Suppressors
Proto-oncogenes normally promote cell division; when mutated into oncogenes they act like an accelerator stuck down. Tumor suppressor genes normally restrain division or trigger repair and cell death; losing them is like losing the brakes.
Example: The TP53 gene codes for p53, a protein that halts the cell cycle when DNA is damaged and can trigger apoptosis. When both copies of TP53 are inactivated, damaged cells keep dividing and mutations accumulate.
Cancer as a Multistep Process
Most cancers need several mutations, gained over time, before cells grow uncontrollably and invade. This helps explain why cancer risk rises with age and why reducing exposure to mutagens matters.
How Treatments Target Cancer
Chemotherapy and radiation damage rapidly dividing cells, which is why they also affect hair follicles and the gut lining. Targeted therapies act on a specific molecular change in the tumor, and immunotherapies help the immune system recognize cancer cells.
Example: When evaluating a treatment in a paper, state the molecular target, the evidence from clinical trials and the side effects, rather than simply calling it effective.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Cancer type paper | Mechanism, risk, detection and treatment | Cell biology first, then risk factors, screening and treatment options |
| Treatment evaluation | Interpreting evidence | Explain how it works, what trials show, and its limits |
| Lifestyle analysis | Applying biology to choices | Link each habit to a mechanism and to evidence of risk change |
The Hallmarks of Cancer
A widely used framework, the "hallmarks of cancer" described by Douglas Hanahan and Robert Weinberg, summarizes the capabilities cells acquire as they become cancerous. It is a useful way to organize revision and papers.
- Sustaining signals to grow and divide
- Evading signals that suppress growth
- Resisting cell death
- Unlimited replication
- Inducing a blood supply (angiogenesis)
- Invading tissue and spreading (metastasis)
Later versions of the framework added further hallmarks and enabling characteristics, such as genome instability and avoiding immune destruction. Linking a treatment to the hallmark it targets is a strong way to evaluate it.
Screening and Early Detection
Screening looks for cancer, or changes that may become cancer, in people without symptoms. It links directly to UMGC's aim of applying cancer biology to lifestyle and health choices.
When you discuss a screening test, cover what it detects, who it is recommended for, and its trade-offs, including false positives and overdiagnosis. Current recommendations from public health bodies are the best source, since guidance changes over time.
Where Students Get Stuck
- Molecular detail. Learn a few key genes well (TP53, RAS, BRCA1) rather than many superficially.
- Overstated claims. Avoid saying a food or supplement "prevents cancer". Describe the size and quality of the evidence.
- Poor sources. Use cancer research organizations, government agencies and peer-reviewed reviews.
- Treatment lists. Explain how each treatment acts on cancer biology.
Study Tips for BIOL 304
- Revise the normal cell cycle and its checkpoints first; cancer is that system failing.
- Make an accelerator-and-brakes diagram for oncogenes and tumor suppressors.
- For each cancer you study, note one key mutation, one risk factor and one screening method.
- Read treatment news critically: what is the target, and what stage of trial is the evidence from?

Frequently Asked Questions
No. UMGC says it serves both science and non-science majors.
UMGC states it is to apply knowledge of cancer biology to adopt appropriate lifestyle strategies and evaluate current treatments.
No. UMGC allows credit for only one of the two.
It helps, but the course is designed for non-science majors too. Revising the cell cycle and basic DNA structure is a good start.
Common cancers with clear screening and treatment evidence, such as breast, colorectal or lung cancer, have strong literature.
Yes. We review accuracy, sourcing and structure and explain any corrections.
