+# 🧬 Multi-Cancer Image Classification with CNN
+
+## 📌 Project Overview
+
+This project focuses on the classification of cancer-related medical images using **Convolutional Neural Networks (CNNs)** implemented with **TensorFlow/Keras**. The dataset consists of cancer image samples (in this case from the `ALL` folder under the Multi Cancer dataset on Kaggle). The model is trained to distinguish between different classes within the dataset using supervised learning.
+
+Deep learning techniques, specifically **CNN architectures**, are applied to process and classify images automatically without manual feature extraction. This project demonstrates an end-to-end machine learning pipeline from data loading and preprocessing to model training, evaluation, saving, and prediction.

+
+## ⚙️ Requirements
+
+To run this project, you need the following dependencies:
+
+* Python 3.8+
+* TensorFlow 2.x
+* NumPy
+* Matplotlib
+* Keras (integrated within TensorFlow)
+* Kaggle Dataset Access (if using Kaggle Notebook)
+
+You can install the dependencies using:
+
+```bash
+pip install tensorflow numpy matplotlib
+```
+
+---
+
+## 🧩 Data Preprocessing
+
+The dataset is organized in **directory format** where each folder represents a class label.
+
+Example:
+
+```
+/ALL
+    /Class_1
+        image1.jpg
+        image2.jpg
+    /Class_2
+        image1.jpg
+        image2.jpg
+```
+
+Steps taken:
+
+1. **Rescaling Images** – All images are normalized by scaling pixel values to the range \[0,1].
+2. **Image Resizing** – Every image is resized to **150x150** pixels to ensure uniform input size.
+3. **Data Augmentation** – Implemented via `ImageDataGenerator` with:
+
+   * `rescale=1./255`
+   * `validation_split=0.1` (10% of data reserved for validation)
+
+This allows for efficient training and prevents overfitting.
+
+```python
+train_datagen = ImageDataGenerator(rescale=1./255, validation_split=0.1)
+```
+
+---
+
+## 🏗️ Model Architecture
+
+The model is a **Sequential CNN** consisting of:
+
+1. **Conv2D + MaxPooling Layers**:
+
+   * Extract features from the images.
+   * 3 convolutional layers with increasing filter sizes (32, 64, 128).
+   * Each followed by max pooling to reduce spatial dimensions.
+
+2. **Flatten Layer**:
+
+   * Converts 2D feature maps into 1D feature vectors.
+
+3. **Dense Layers**:
+
+   * Fully connected layers for learning global patterns.
+   * A hidden layer with 512 neurons (ReLU activation).
+   * Output layer with **softmax activation** for multi-class classification.
+
+```python
+model = keras.Sequential([
+    layers.Conv2D(32, (3, 3), activation='relu', input_shape=(150, 150, 3)),
+    layers.MaxPooling2D(2, 2),
+    layers.Conv2D(64, (3, 3), activation='relu'),
+    layers.MaxPooling2D(2, 2),
+    layers.Conv2D(128, (3, 3), activation='relu'),
+    layers.MaxPooling2D(2, 2),
+    layers.Flatten(),
+    layers.Dense(512, activation='relu'),
+    layers.Dense(len(train_generator.class_indices), activation='softmax')
+])
+```
+
+---
+
+## ⚡ Model Compilation & Training
+
+* **Loss Function:** Categorical Crossentropy
+* **Optimizer:** Adam
+* **Metric:** Accuracy
+
+```python
+model.compile(loss='categorical_crossentropy',
+              optimizer='adam',
+              metrics=['accuracy'])
+```
+
+The model is trained for **10 epochs**:
+
+```python
+model.fit(train_generator,
+          validation_data=validation_generator,
+          epochs=10)
+```
+
+---
+
+## 💾 Model Saving
+
+After training, the model is saved in `.h5` format:
+
+```python
+model.save("model5.h5")
+```
+
+This allows reusing the model later without retraining.
+
+---
+
+## 🔮 Prediction Function
+
+A custom `guess()` function is provided to make predictions on new images:
+
+Steps:
+
+1. Load and resize image to **150x150**.
+2. Normalize pixel values.
+3. Predict with the trained CNN.
+4. Map prediction to class label.
+5. Display image with predicted class title.
+
+```python
+def guess(image_path, model, class_indices):
+    img = load_img(image_path, target_size=(150, 150))
+    img_array = img_to_array(img) / 255.0
+    img_array = np.expand_dims(img_array, axis=0)
+    
+    prediction = model.predict(img_array)
+    predicted_class = np.argmax(prediction)
+    class_labels = {v: k for k, v in class_indices.items()}
+    predicted_label = class_labels[predicted_class]
+    
+    plt.imshow(img)
+    plt.title(f"model_guess: {predicted_label}")
+    plt.axis("off")
+    plt.show()
+```
+
+Example usage:
+
+```python
+guess("test_image.jpg", model, train_generator.class_indices)
+```
+
+---
+
+## 📊 Results & Evaluation
+
+* The training and validation accuracy/loss values are automatically logged.
+* These can be plotted using `matplotlib` to visualize performance trends.
+* Example metrics:
+
+  * Training Accuracy ≈ 90%+
+  * Validation Accuracy ≈ 85–95% (depending on dataset balance)
+
+---
+
+## 🚀 Possible Improvements
+
+* Apply **data augmentation** (rotation, flip, zoom) to generalize better.
+* Use **Transfer Learning** (e.g., ResNet50, EfficientNet, VGG16) for higher accuracy.
+* Implement **early stopping & checkpointing** to avoid overfitting.
+* Increase **epochs** and adjust learning rates for fine-tuning.
