Malignant neoplasm progression adverse event reports that record this term
- Kind of term
- MedDRA preferred term
What a report is
A report is not proof that the drug was the cause of the event.
FDA says:
Adverse event reports submitted to FDA do not undergo extensive validation or verification. Therefore, a causal relationship cannot be established between product and reactions listed in a report. While a suspected relationship may exist, it is not medically validated and should not be the sole source of information for clinical decision making or other assumptions about the safety or efficacy of a product. Additionally, it is important to remember that adverse event reports represent a small percentage of total usage numbers of a product. Common products may have a higher number of adverse events due to the higher total number of people using the product.

FDA also says:
There is no certainty that the reported event (adverse event or medication error) was actually due to the product. FDA does not require that a causal relationship between a product and event be proven, and reports do not always contain enough detail to properly evaluate an event. The information in these reports has not been scientifically or otherwise verified as to a cause and effect relationship and cannot be used to estimate the incidence of these events.

Do not rely on openFDA to make decisions regarding medical care. While we make every effort to ensure that data is accurate, you should assume all results are unvalidated.

Reports on file
From January 2004 to June 2026, FDA received 100,310 adverse event reports that record the MedDRA preferred term Malignant neoplasm progression. The person who codes a report selects the term that agrees best with the description of the reporter.
FDA received 8,084 reports in the 12 months to June 2026 and 6,944 in the 12 months before. FDA releases FAERS data every quarter, so the newest months are not complete. They grow in later releases.
By reports in the 12 months to June 2026, this term was number 84 of 1,436 reaction terms with a page. Of the 1,332,454 drug reports that FDA received in the 12 months to June 2026, 8,084 (0.6%) record this term. Reports for male patients were 44.7% of the reports that record this term and 34.6% of all drug reports.
The number of people who use the product is not in the data. A count is not a rate.

Reported Reactions. Malignant neoplasm progression: adverse event reports that record this term. https://reportedreactions.com/reaction/malignant-neoplasm-progression/ Source: U.S. Food and Drug Administration, openFDA Drug Adverse Event (FAERS) files, release of . Reports received through .
Where the data come from
The counts come from the openFDA Drug Adverse Event (FAERS) bulk files, release of 29 Oct 2026. The files have the reports that FDA received through 30 Jun 2026. A drug name is the name on the report. The site matches it to a brand name or a generic name of the National Drug Code Directory of 2 Nov 2026. A class is the pharmacologic class (EPC) of the FDA label.
The count has the reports with each spelling of one MedDRA preferred term. The site does not publish a report narrative, a lot number, a detail of a patient or the identity of a reporter. The record of FDA is the authority. See how the site counts reports, the data sources and the corrections page.
Questions
What does Malignant neoplasm progression mean in an adverse event report?
It is a MedDRA preferred term. FDA codes the description of a reporter with the MedDRA dictionary. The openFDA files do not have the description itself, and this site does not show it.
Does a drug in the table mean that the drug was responsible for this reaction?
No. FDA says:
No individual drug is connected to any individual reaction.
Source: openFDA, Drug Adverse Event Overview. The site read the page on .
When a report lists multiple drugs and multiple reactions, there is no way to conclude from the data therein that a given drug is responsible for a given reaction.

What does this page tell a person who has this symptom?
This page gives counts of reports. It cannot assess a person. A pharmacist or a clinician can assess a person.
If this is a medical emergency, please call 911.
