Recently I came across this study:
I strongly believe that this result or conclusion may be biased and requires more research and a greater study size, internationally. I believe this study does not appropriately define a greater risk for lymphoma and tattoos; however, it does crack the door open for the question. Hopefully someday soon we get more research on this subject.
In summary:
The article titled "Tattoos as a Risk Factor for Malignant Lymphoma: A Population-Based Case-Control Study" investigates the potential link between tattoos and the risk of malignant lymphoma.
Key Findings:
Background: The study highlights the growing popularity of tattoos and the presence of carcinogenic chemicals in tattoo ink, such as primary aromatic amines and polycyclic aromatic hydrocarbons. These substances can be transported to lymph nodes, but the long-term health effects are unclear.
Methods: The researchers conducted a case-control study using data from the Swedish National Cancer Register (2007-2017) and surveyed individuals aged 20-60 years. Data from 1,398 lymphoma cases and 4,193 controls were analyzed.
Results:
Tattoo prevalence was higher in lymphoma cases (21%) compared to controls (18%).
An increased risk of lymphoma was observed in tattooed individuals (IRR = 1.21; 95% CI 0.99-1.48).
The risk was highest for those who got a tattoo within two years of the diagnosis (IRR = 1.81; 95% CI 1.03-3.20).
The risk decreased for those with tattoos for 3-10 years but increased again for those with
The article does not specify which tattoo inks or brands were studied. However, it mentions that tattoo ink often contains carcinogenic chemicals, such as:
Primary aromatic amines
Polycyclic aromatic hydrocarbons (PAHs)
Metals
These substances are known to be harmful and can migrate to lymph nodes, but the study focused on the overall exposure to tattoos, not on analyzing specific ink formulations or brands.
Primary aromatic amines (PAAs) are a group of chemical compounds that are commonly used in synthetic dyes and pigments, including those found in tattoo ink.
Which ink colors are more likely to contain PAAs?
Black ink (contains carbon-based PAHs and amines)
Red and yellow inks (contain azo dyes)
Blue and green inks (contain copper phthalocyanine, which can degrade into PAAs)
Polycyclic Aromatic Hydrocarbons (PAHs) in Tattoo Ink
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of toxic, carcinogenic chemicals made up of multiple fused aromatic rings.
🔬 What are PAHs?
They are by-products of burning organic materials, like coal, oil, tobacco, and carbon-based black tattoo ink.
Black ink, often made from carbon black or soot, is the most common source of PAHs in tattoos.
· Metals in Tattoo Ink and Their Link to Cancer
· Tattoo inks, especially colored pigments, contain heavy metals that stay in your skin and lymph nodes for years. Many of these metals are toxic, carcinogenic, and linked to lymphoma and other cancers.

Common Heavy Metals in Tattoo Ink:
Metal | Ink Color | Health Risk |
Arsenic (As) | Black, Red | Carcinogen (linked to skin and blood cancer) |
Lead (Pb) | Black, Green | Neurotoxic, linked to lymphoma |
Cadmium (Cd) | Yellow, Red | Carcinogen (lung and lymphoma risk) |
Nickel (Ni) | Green, Black | Carcinogen, triggers allergic reactions |
Chromium (Cr VI) | Green, Black | Carcinogen, linked to lymphoma |
Mercury (Hg) | Red | Highly toxic, damages nerves |
Cobalt (Co) | Blue, Green | Linked to skin inflammation and cancer |
Aluminum (Al) | White, Blue, Violet | Linked to neurotoxicity |
Titanium Dioxide (TiO₂) | White, Light Colors | Inflammatory, found in lymph nodes |
