During or after treatment, some individuals notice that their skin becomes drier than before. It may also feel itchy, slightly flaky, or more sensitive.
Some people find that skincare products they used comfortably in the past suddenly feel unsuitable, or that their skin reacts more strongly to weather changes.
These changes are not uncommon during the recovery phase and are often related to temporary adjustments in the skin’s barrier function.

After completing treatment, some individuals notice that they become short of breath after walking only a short distance, their heart rate feels faster than before, or they occasionally experience dizziness.
These changes are often mistaken for simple lack of rest. However, the underlying causes may involve more specific physiological factors.

In discussions about cancer-related nutrition and supportive therapies, “antioxidants” are frequently mentioned. Among them, glutathione is one of the body’s most important endogenous antioxidants.
Many patients hear about glutathione during treatment, yet fewer fully understand how it functions in the body and when supplementation may or may not be appropriate.

Vitamin D is one of the most frequently discussed nutrients in cancer-related nutrition.
Beyond its well-known role in bone health, vitamin D is also involved in immune regulation, cellular differentiation, and inflammatory balance. For this reason, many patients undergoing treatment or in recovery begin to wonder:
Am I deficient in vitamin D? Should I be supplementing?

Among supportive therapies discussed in the context of cancer care, high-dose vitamin C intravenous (IV) therapy remains one of the most debated options.
Some believe it may help improve fatigue or overall vitality, while others question whether it could interfere with primary treatments. In a landscape filled with mixed information, the key is not to take sides—but to understand its biological rationale and appropriate clinical context.

During cancer treatment, inflammation is almost always part of the physiological picture.
The tumor itself, chemotherapy, radiation therapy, and even prolonged psychological stress can all contribute to a state of chronic inflammation.
When inflammation persists, patients may experience:
• Ongoing fatigue
• Reduced appetite
• Muscle loss
• Weight fluctuations
• Unstable immune function
For this reason, managing inflammatory balance—without interfering with primary treatment—has become an important area of supportive care.

After completing major cancer treatments, many patients notice a disconnect:
Medical reports may appear stable, yet their physical strength does not seem to return.
Shortness of breath while walking, reduced concentration, persistent fatigue, and difficulty handling daily activities are common concerns. This slower-than-expected recovery is not unusual in clinical practice.
Often, the issue is not simply general weakness — it may be related to nutritional status and red blood cell function.

During cancer treatment, the body is not only coping with the disease itself but also with the metabolic stress and side effects caused by surgery, chemotherapy, or radiation therapy.
Throughout this process, certain vitamins may be depleted more quickly, absorbed less efficiently, or consumed in lower amounts due to dietary changes.
As a result, the risk of vitamin deficiencies is often higher than in the general population.

During cancer treatment, many people focus heavily on medications, side effects, and test results, yet often overlook one fundamental yet critical factor — protein intake.
In reality, during both the treatment phase and recovery period, protein is not just “part of nutrition” — it is a core building block for the body’s repair and maintenance of essential functions.
