Final answer:
Radiation therapy can lead to sterility and skin changes, while chemotherapy might cause hair loss and bone marrow cell depletion, highlighting the challenge of targeting cancer cells without affecting normal cells.
Step-by-step explanation:
The treatment modalities referenced likely pertain to therapies for conditions such as cancer; these can include radiation therapy and chemotherapy. It's important to understand that both therapies can produce side effects impacting various body systems due to their nonspecific targeting of rapidly dividing cells.
For radiation therapy, two side effects may include:
- Sterility, particularly if reproductive organs are exposed to radiation.
- Skin changes, such as dryness and itching, or loss of sensation in the irradiated area.
For chemotherapy, two side effects could be:
- Damage to healthy cells in systems with rapid cell turnover, like hair loss due to destruction of hair follicle cells.
- Depletion of bone marrow cells, leading to conditions such as anemia or compromised immune functions.
These side effects underline the difficulties in treating cancers and the need for therapies that specifically target cancer cells without harming normal, healthy cells.
