**Core Concept**
Cadmium is a toxic heavy metal that can cause various health problems, including cancer, upon prolonged exposure. Occupational exposure to cadmium is a significant risk factor for certain types of malignancies. **Carcinogenesis** due to cadmium involves multiple pathways, including damage to DNA and disruption of cellular homeostasis.

**Why the Correct Answer is Right**
Cadmium is known to be associated with an increased risk of **prostate cancer** and **lung cancer**. The exact mechanism involves the ability of cadmium to induce **genotoxic** effects, including DNA damage and epigenetic alterations. Cadmium also disrupts normal cellular functions by interfering with **zinc-dependent enzymes** and **cell signaling pathways**.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because, while cadmium exposure is harmful, the specific association with the mentioned malignancy is not as strongly established as with other types of cancer.
**Option B:** This option is incorrect as it does not accurately represent the primary malignancy associated with cadmium exposure.
**Option C:** This option is also incorrect for similar reasons, lacking a direct, well-documented link to cadmium exposure.

**Why Each Wrong Option is Incorrect** for the remaining options is not applicable due to the absence of explicit options.

**Clinical Pearl / High-Yield Fact**
It's crucial to remember that **heavy metal exposure**, including cadmium, can have severe health consequences, including increased cancer risk. Recognizing occupational hazards is key to preventing such exposures.

**Correct Answer:** D. Prostate and lung cancer.
